As the animated version of Stephen Chow's 2008 hit comedy CJ7, CJ7: The Cartoon loosely adopts the original plot of how a father and a son accidentally pick up an alien named CJ7. The film has a newly developed story line during which CJ7 protects the environment and saves the earth.

When a kingdom gets cursed by One-Eye (Ian Hecox), it's up to Freddy (Anthony Padilla), Frog Princess (Ambyr Childers) and Ababwa (Jon Lovitz) to make things right again. The mighty frogs set off on an adventure to stop the curse, and things begin to get harder along the journey. Join them on their mission to save the kingdom!
