The skeleton's voice was the funniest part, honestly.
"I sleep now!"
I've reviewed it, and am one of the ones who thinks it plays on making fun of the genre too much.
My favorite character is Animala, and any favorite part would have to involve her, mostly due to her "Rowr!" which was series enough to be really funny. She's also the catalyst in the humorous meal scene, so I'll nominate that for the funniest part of the movie.
LOL...that reminds me of the bit where Animala leads the scientist around with the box ....geez,that cracks me up!
