- This film was a request from BrerJake90 who co-directed Pooh's Adventures of Osmosis Jones with DisneyDaniel93.
- The reason why Jessie, James, and Meowth of Team Rocket are in this film is because Ash and the gang are the only Pokemon characters guest starring in Pooh's Adventures of Osmosis Jones.
- Like DisneyDaniel93's film, Pooh's Adventures of Osmosis Jones, this is an NTSC film with NTSC bits from The Land Before Time movies, Thumbelina, South Park: Bigger, Longer & Uncut, Space Jam, Looney Tunes: Back in Action, The Black Cauldron, the Aladdin trilogy, Free Willy 1-3, the Pokémon movies, The Swan Princess movies, The Goonies, Dumbo, Dinosaur, the Scooby-Doo movies, the All Dogs Go to Heaven movies, The Nightmare Before Christmas, and Mickey, Donald, Goofy: The Three Musketeers.
- Both The Land Before Time VIII: The Big Freeze and Osmosis Jones were released in 2001.
- The reason why Pete is guest starring in this film is because Mickey Mouse, Donald Duck, and Goofy will be guest starring in Bloom's Adventures of Osmosis Jones without him.
