Trivia: The movie contains a spoof of Saving Private Ryan, where Manny is hit by a geyser and temporarily loses his hearing. Incidentally, the German voice for Manny, Arne Elsholtz, also synchronizes Tom Hanks, who also stars in that movie, which creates an inside joke by happenstance in the German version.
Trivia: When the "Dragons" are being released around the world, you see a baby carriage nearly falling into one of the cracks that forms in the ground, only to be saved at the last minute. The baby-crying sound effects were actually provided by Selma Blair, who does the voice of Liz Sherman (and also played her in the live action film), after the makers realized she could do a perfect impression of an infant crying.
Trivia: Tiger the cat was originally going to be a tabby, but when the writers found out that the actor providing the voice for him was of the Persian nationality, they made Tiger a Persian.
Trivia: Some say that Leroy is experiment 628. Some people haven't noticed that in the episode with 627, at the end of the episode, Jumba had said, "Maybe next time will be better" as he places a pod that said 628. So 628 had already been created. He was never shown in the entire series, though Leroy is 629.
