Behind the scenes

• The opening theme gag is of Speed Buggy backing into a building.

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.
