I had posted about this here last Friday. But the next day I realized that I had posted in the wrong sub-forum. I deleted that thread and reposted in the correct sub-forum. But the thread didn't show up. Try again:

Cartoon Network's new Sunday morning schedule:

The Scooby Doo Show airs at 8:00 AM and 8:30 AM.
A direct-to-video Scooby Doo movie airs at 9:00 AM.
The Heroic Quest of the Valiant Prince Ivandoe or Jellystone! airs as filler after the movie.
The Looney Tunes Show airs at 11:00 AM, 11:30 AM and 12:00 PM.
The Tom and Jerry Show airs at 12:30 PM and 1:00 PM.
Tiny Toons Looniversity (one episode from Season One, one episode from Season Two) airs at 1:30 PM and 2:00 PM.

When I watched last Sunday morning, the "coming up next" was for Scooby Doo and Guess Who?, so I thought that my cable TV box's guide was wrong. But Cartoon Network did indeed show two Scooby Doo segments from The Scooby Doo/Dynomutt Hour (retitled The Scooby Doo Show for syndication). This Sunday, Cartoon Network is showing one Scooby Doo segment from Scooby's All Star Laff-A-Lympics (retitled The Scooby Doo Show for syndication) and one episode from what has been called the "third season" of Scooby Doo, Where Are You?, from the 1978-79 season. For the original Saturday morning broadcasts (which I watched), the original Scooby Doo, Where Are You? opening from 1969 was reused. The title card used the same background painting and lettering that would later be used for Scooby Doo and Scrappy Doo and The Richie Rich/Scooby and Scrappy Doo Show, but with the whole gang running across the bottom of the screen. I'm curious to see what opening will be used for Cartoon Network's Saturday morning broadcasts.

EDIT: Cartoon Network had corrected the "coming up next" to The Scooby Doo Show. Both episodes that aired this morning had the opening from The Scooby Doo Show that was used in syndication. The episode from 1978, "A Highland Fling With a Monstrous Thing" had the title card format that I remember. (But I had forgotten that the Mystery Machine is in it.)

Scooby Dum was in the episode that aired at 8:30 AM, "Vampire Bats and Scaredy Cats". Fred calls the two dogs "the Scooby brothers". But I remember them being called "the Scooby cousins". I'm guessing that it was a writer's error.

EDIT #2: Cartoon Network goofed again. The "coming up next" was for Scooby Doo and Guess Who?, even though they showed two Scooby Doo segments from The Scooby Doo/Dynomutt Hour, including the one that introduced Scooby Dum, "The Gruesome Game of the Gator Ghoul". The opening titles of this one had been sped-up, but everything else was normal speed.

EDIT #3: Cartoon Network was back to The Scooby Doo Show for the "coming up next". Two more Scooby Doo segments from The Scooby Doo/Dynomutt Hour were shown, including another one with Scooby Dum, "The Headless Horseman of Halloween". Scooby Dum is called Scooby Doo's brother and Scooby Doo's cousin in the same episode. And I recognized Janet Waldo voicing the great great granddaughter of Ichabod Crane. One of the characters in the other episode, "Scared a Lot in Camelot" was "Uncle Shagworthy", who was voiced by Casey Kasem. So Scooby Doo Mystery Incorporated wasn't the first time that Casey Kasem voiced one of Shaggy's relatives.

EDIT #4: The first three "coming up next" said The Scooby Doo Show, but the fourth (and final) one said Scooby Doo and Guess Who?. Two more Scooby Doo segments from The Scooby Doo/Dynomutt Hour. No Scooby Dum.

EDIT #5: Every "coming up next" was for The Scooby Doo Show, so maybe Cartoon Network has finally got things straightened out. Two more Scooby Doo segments from The Scooby Doo/Dynomutt Hour. The first one, "Mamba Wamba and the Voodoo Hoodoo", recycled the zombie character design from an episode of Scooby Doo, Where Are You?, though with different clothes. (And in one scene, Shaggy and Scooby put a dress on the zombie.) In the second one, "A Frightened Hound Meets Demons Underground", statues of a werewolf and a witch in a museum also looked like recycled character designs from Scooby Doo, Where Are You?. No Scooby Dum.

EDIT #6: Two more Scooby Doo segments from The Scooby Doo/Dynomutt Hour. No Scooby Dum.

EDIT #7: Two more Scooby Doo segments from The Scooby Doo/Dynomutt Hour. (The second episode, "The Ghost That Sacked the Quarterback", aired on Boomerang on Super Bowl Sunday this year because it's football-themed.) No Scooby Dum.

EDIT #8: Two more Scooby Doo segments from The Scooby Doo/Dynomutt Hour. The second episode, "The Spirits of '76", referenced the Bicentennial. No Scooby Dum.

EDIT #9: Two Scooby Doo segments from Scooby's All-Star Laff-A-Lympics. One of the characters in the first episode,
"The Curse of Viking Lake", is Velma's Uncle John, who wears glasses just like the ones Velma wears. No Scooby Dum.

EDIT #10: Two more Scooby Doo segments from Scooby's All-Star Laff-A-Lympics. The first episode, "The Creepy Heap From the Deep", had a title card, but the second episode, "The Chiller Diller Movie Thriller", didn't have one. "The Chiller Diller Movie Thriller" is an episode that I well remember from my childhood. In addition to Scooby Dum, this episode also has another cousin, Scooby Dee. I'm guessing that her little ol' Southern voice was done by Janet Waldo.

EDIT #11: It was back to every "coming up next" being for Scooby Doo and Guess Who? instead of for The Scooby Doo Show. Two more Scooby Doo segments from Scooby's All-Star Laff-A-Lympics. The first episode, "The Spooky Case of the Grand Prix Race", had a title card, but the audio was absent. The second episode, "The Ozark Witch Switch", didn't have a title card. It was about the descendants of the Hatfields and the McCoys, so Janet Waldo got to use her little ol' Southern voice again. No Scooby Dum.

EDIT #12: Every "coming up next" was for The Scooby Doo Show. One episode from Scooby's All-Star Laff-A-Lympics and one episode from the "third season" of Scooby Doo, Where Are You?. Both episodes had a title card. The monster in the first episode, "Creepy Cruise" looked like it was related to Space Ghost's nemesis Zorak. The monster supposedly came from over 5000 years in the future, so "back to the future" was heard more than once. One of the incidental characters in the second episode, "Watch Out For the Willawaw!", was Velma's Uncle Dave, who was voiced by Casey Kasem, using a voice similar to the one he used for Robin in Superfriends. No Scooby Dum.

EDIT #13: Two episodes from the "third season" of Scooby Doo, Where Are You?. In the first episode, "To Switch A Witch", Janet Waldo voiced the descendant of a witch who was burned at the stake in 1578, as well as the "witch", who turned out to be the long-lost twin sister of the descendant. The man leading the "witch hunt" that targeted the descendant was voiced by Lennie Weinrib. This was less than a year before he started voicing "the most hated cartoon character of all time". No Scooby Dum.

EDIT #14: Two more episodes from the "third season" of Scooby Doo, Where Are You?. The second episode, "A Highland Fling With A Monstrous Thing", was a "repeat" since Cartoon Network initially didn't air the episodes in order. In the first episode, "The Creepy Case of Old Iron Face", I heard Lennie Weinrib again, as an old sea captain who turns out to be a detective in disguise. No Scooby Dum.

EDIT #15: Two more episodes from the "third season" of Scooby Doo, Where Are You?. In the first episode, "A Scary Night With A Snow Beast Fright", in one scene Velma speaks with Daphne's voice and Daphne speaks with Velma's voice. And I thought that I heard Mel Blanc's famous "sputtering" sound effects when Scooby is "rowing" a kayak through snow. I suppose it's possible, since Mel Blanc was doing Captain Caveman and the Teen Angels at this time. No Scooby Dum.

EDIT #16: Two more episodes from the "third season" of Scooby Doo, Where Are You?. The second episode, "The Creepy Creature of Vulture's Claw", had problems with the cel painting. Sometimes Fred's shirt was a very light gray instead of white. Sometimes Scooby's head was a slightly lighter shade of brown than the rest of him. In some scenes with the whole gang together, the same color cel paint wasn't used on everyone's faces. (And that's not all.) Plus one scene had some off-model animation. (And I don't mean Velma's freckles randomly appearing and disappearing.) Of course I didn't notice any of this when I watched the original broadcasts when I was ten years old. No Scooby Dum.

EDIT #17: Two more episodes from the "third season" of Scooby Doo, Where Are You?. The "phantom" in the second episode, "The Diabolical Disc Demon", was obviously inspired by KISS (over 35 years before the Scooby gang actually did a crossover with KISS in one of the direct-to-video movies), except that its hair was red and orange instead of black. Both episodes suffered from the same cel paint problems as "The Creepy Creature of Vulture's Claw". Sometimes Fred's shirt was very light gray, sometimes it was white. Also, in one scene in "The Diabolical Disc Demon", Daphne's legs were painted the same color as her face and hands instead of lavender, like she forgot to wear nylon stockings. No Scooby Dum.

EDIT #18: Two more episodes from the "third season" of Scooby Doo, Where Are You?. The title cards for both episodes had the Mystery Machine in the bottom right corner, but no one ran across the bottom of the screen. More of the same cel paint problems. In one scene, Fred's head was so much of a lighter color than the rest of him that it almost looked radioactive. This also happened with Daphne and Velma. The whole gang (including Scooby) is wearing full scuba diving gear, including wetsuits, in part of the second episode, "The Beast Is Awake In Bottomless Lake". But in one brief shot in which Shaggy and Scooby are trapped inside something, Shaggy is wearing his usual clothes. In this same episode, Scooby says "Dog? What dog?". I thought that originated in the modern direct-to-video Scooby Doo movies. No Scooby Dum.

(I didn't get to watch the two episodes that aired on Cartoon Network on the morning of October 13th because I was stuck at my sister's house with no cable TV and no electricity because of Hurricane Milton.)

EDIT #19: One episode from the "third season" of Scooby Doo, Where Are You and a "repeat" of an episode from Scooby's All-Star Laff-A-Lympics now that CN has shown all 40 episodes in this time slot. In the "new" episode, "The Warlock of Wimbledon", Velma suspects that her friend's glasses have been replaced with a pair that's been tampered with, so she lets him borrow her glasses...then she pulls out a spare pair and puts them on. So where were those spare glasses all of the other times that she lost her glasses, before and since then? No one ran across the bottom of the title card of this episode. More cel paint problems, especially with Fred's shirt. Scooby Dum wasn't in "The Warlock of Wimbledon", though he was in the "repeat", "The Chiller Diller Movie Thriller", along with Scooby Dee. (You'd think that CN would have shown "The Headless Horseman of Halloween" as the "repeat".)

Also, since Boomerang aired a 24-hour marathon of The Scooby Doo Show on October 27th, I got to watch the two episodes that I missed the CN Sunday morning broadcasts of because of Hurricane Milton, which were both from the "third season" of Scooby Doo, Where Are You?. The whole gang ran across the bottom of the title card of the first episode, "Scooby's Chinese Fortune Kooky Caper", but didn't run across the bottom of the title card of the second episode, "A Menace in Venice". One of the supporting characters in "A Menace in Venice" may have been voiced by Lennie Weinrib, though I'm not positive. More cel paint problems, once again especially with Fred's shirt. No Scooby Dum.

Thanks to Cartoon Network (and Boomerang), I have now watched the Scooby Doo segments from all 40 episodes of The Scooby Doo/Dynomutt Hour, Scooby's All-Star Laff-A-Lympics and the "third season" of Scooby Doo, Where Are You?. Scooby Dum was in only four of these 40 episodes. Whereas Scrappy Doo was shoved down everyone's throats for seven seasons, plus three made-for-TV movies. I suppose it wouldn't have been so bad if the format hadn't changed so drastically after the first season, going from the whole gang solving mysteries to just Shaggy, Scooby and Scrappy having comic misadventures in three short segments in a half hour, including dealing with bullies, trying new jobs, and sometimes encountering real monsters. (And Scooby and Shaggy really took a beating in some of these episodes, especially Scooby. I can remember episodes that ended with Scooby and Shaggy in hospital beds with broken limbs.) Eventually Daphne returned, they were back to solving mysteries, and there were occasional appearances by Fred and Velma, though this happened after I had joined a Saturday morning bowling league and wasn't regularly watching Saturday morning cartoons. (So in addition to missing out on new episodes of Scooby Doo, I also missed out on the second season of "Laverne and Shirley in the Army", the Mork and Mindy Saturday morning cartoon, the second season of Saturday Supercade, Turbo Teen, and probably more that I'm forgetting.) Then things got really weird with The 13 Ghosts of Scooby Doo (including a major makeover for Daphne), though I only watched a single episode because by then I was at Tusculum College. Thankfully the franchise eventually reverted back to the whole gang solving mysteries (and Scooby walking on all fours instead of walking on his hind legs like he did during most of the Scrappy Doo era), first with A Pup Named Scooby Doo, then with the "modern" direct-to-video Scooby Doo movies and the 21st century Scooby Doo TV series, which also seem to have a higher budget.

One other thing I noticed is that in The Scooby Doo Show, Scooby says "Shaggy" instead of "Raggy". I don't know when Scooby reverted back to saying "Raggy".

(I didn't think that this was worth starting a new thread about it.)

Starting tomorrow (July 22nd), Be Cool, Scooby Doo! gets added to Cartoon Network weekday schedule. One episode airs at 11:30 AM, after two back-to-back episodes of Scooby Doo and Guess Who?.

(I've only watched one episode of Be Cool, Scooby Doo!. I do NOT like the character designs. (Someone here said that it made the characters look like "residents of Quahog".) Maybe that's why it's currently only being shown on weekends on Boomerang. Thankfully Scooby Doo and Guess Who? reverted to the original character designs from 1969. And the direct-to-video Scooby Doo movies never used them.)

EDIT: On Friday, August 2nd, Total Drama Island airs at 11:30 AM on Cartoon Network instead of Be Cool, Scooby Doo!.

Scrappy Doo's return to Cartoon Network continues. Starting Monday, February 24th, The New Scooby Doo Mysteries airs at 11:30 AM and 12:00 PM on weekdays on CN, replacing Scooby Doo, Where Are You? and The Scooby Doo Show.

(Interesting that they're starting with the Season Two episode "Happy Birthday, Scooby Doo", which brought back Fred and Velma.)

Starting March 1st, Scooby Doo Mystery Incorporated airs at 2:30 PM and 3:00 PM on Saturdays, replacing What's New Scooby Doo?.

And Be Cool, Scooby Doo! no longer airs at 6:00 AM and 6:30 AM on Saturdays. It's been replaced by Adventure Time.

Also, a new half hour Scooby Doo special, Robot Mystery, premieres on Cartoon Network on Sunday, March 2nd, at 7:30 AM, airing in place of an episode of Scooby Doo and Scrappy Doo.

EDIT: Robot Mystery did NOT air on Cartoon Network yesterday morning at 7:30 AM. An episode of Scooby Doo and Scrappy Doo from the first season, "The Scary Sky Skeleton" aired instead.

That didn't last very long. Starting Monday, March 10th, Scooby Doo, Where Are You? returns to Cartoon Network, airing at 11:30 AM and 12:00 PM, replacing The New Scooby Doo Mysteries.

(And CN never aired any Season One episodes of The New Scooby Doo Mysteries, only Season Two episodes.)

Starting Monday, March 24th, Cartoon Network's weekday morning schedule gets an overhaul, including The Scooby Doo Show replacing Scooby Doo, Where Are You?:

New Looney Tunes airs from 6:56 AM to 7:24 AM.

Be Cool, Scooby Doo! airs at 9:28 AM and 10:00 AM.

And the Tom and Jerry shorts from Cartoon Network Asia continue to air as filler on weekday mornings, usually three days a week.

(Also, Scooby Doo Mystery Incorporated has replaced Be Cool, Scooby Doo! at 6:00 AM and 6:30 AM on Sundays. I think this started on March 16th.)
