Everyone expects him, and King Nigel and Queen Elza decide to arrange a ball for the christening of Bob and Sylvia's new baby daughter, Amanda.

[clarification needed] Meanwhile, Corvax, Nigel's former vizier and the villain of the previous film, who was demoted to a cook for failure to stop his computer from producing Sylvia clones, invents an invisibility device.

With his assistant Thimbo "the Terrible", a thief on parole, he schemes to kidnap Amanda so he can get revenge on Bob for tricking him and taking Sylvia away from him.

In the end, Corvax and Thimbo ride with sheep to receive the unknown ultimate punishment offscreen (although it is accordingly known that, in Britain, this means 250 years in prison).

As in the first film, a bicycle-riding human named Norman is the star of a series of skits that periodically interrupt the main story to teach the viewers how to say certain things in different languages as they relate to the scenes they follow.
