Morris and Boris go to the circus as spectators and end up being part of the action.

The Sweet Potato Circus is in trouble, and Louise and her best friend, Stella, will do anything to save their circus--even if it means joining forces with their sworn enemy, Ferret-breath Fernando.

Thanks to her good memory and splendid imagination, Mama Bear and her bear cub have been able to enjoy the circus ... from the outside. But as almost always happens in stories, there is no shortage of the cunning man who wants to profit: the fox tries to collect the amount of the tickets, although the bears did not enter. Oh, fox! You didn't have the wit of daddy bear and you got what you deserved!
