Pooh and his friends look for the April Fool, not aware that it is Christopher Robin playing jokes on them.

Pooh is babysitting Owl's nephew, Dexter, and Roo. They and the rest of the gang are invited to Christopher Robin's house so they could see his science project, which is an insect. But the gang accidentally lets the bug loose and soon agree that they will find a replacement bug for Christopher Robin.

Tigger loses his voice, and Pooh and the gang try to find the 'Nobody' that took it. Meanwhile, Gopher tries to get rid of the crows bothering him, and Rabbit tries to find his vegetables.
