Dates are in order of release:


 * United States: July 29, 2021 on HBO Max; September 25, 2021 on Cartoon Network
 * Canada: October 24, 2021 at 9 am on Teletoon

Errors

 * How did some of the characters that were turned into Jell-O inside Jellystone Hospital get outside?
 * Cindy has Bleep in a jar, but his arrival only happens later on in "Mr. Flabby Dabby Wabby Jabby."
 * Smith is still referred to Ranger Smith in the credits despite no longer working at the park. Probably to not confuse anyone.
