To avoid prison, a gang of notorious animal criminals pretend to seek being rehabilitated, only for their leader to secretly find that he genuinely wants to change his ways.
 
Based on the children's book series of the same name written by Aaron Blabey, this film has done its fans justice.  The animation is excellent, the story is original and the movie checks all the four "F's" - Fantasy Fun For Family.
 
FUN FACT:  When Wolf proposes the gang to pretend to be good, Mr. Shark tells the story about a brother who had an anchor falling on his head. This refers to the previous DreamWorks Animation film Shark Tale (2004), which had two shark brothers: Frankie who died from an anchor dropping on him, and his brother Lenny, a good guy, who briefly pretends to be bad.
