However, Mr. Whiskers' brain agrees with her, so he decides to leave his brain and head off to live his own life. Mr. Whiskers begins to become depressed as he feels lonely without his brain inside of his head, so Brandy decides to head off to find Mr. Whiskers' brain in order to return it to the rightful place where it belongs, though how will she manage to convince his brain to go back to the place he hates?
Goofy-bunny Mr. Whiskers meets prissy-pooch Brandy Harrington within a cargo hold of a plane. When Whiskers mistakenly opens the hatch door, the pair is dropped into the Amazon Rainforest with no way home. Desperate and angry, Brandy makes a deal with the dictator lizard Gaspar: a way back to civilization in exchange for Mr. Whiskers as his dinner. In the end, she loses her way home, but truly gains a friendship with Lola Boa and Mr. Whiskers.
Brandy volunteers to watch a crocodile’s eggs for the day, but when Lola Boa and the Toucan Twins invite her to hang out, she leaves Whiskers in charge.
