A jokester worm finds out that friendship means more than just play in this candy-colored story!

Wiggler loves a good laugh!

Thanks to a joke book that she took out from the library, her day is all fun and games. Everyone in town enjoys her new jokes . . . until she accidentally hits a nerve and makes her friend Roro angry. But why? Did she forget part of the joke? Did she tell the punchline wrong? What could possibly be the problem?

After a nudge from a four-legged friend, Wiggler realizes that jokes aren't always helpful, especially when someone is sad or stressed. Wiggler tracks down Roro to make things right—and Roro comes up with an excellent joke of his own.
