Mouse, Hedgehog, Rabbit, Squirrel, and Snake are friends. But one day Mouse hears from Skunk (who heard it from Fox) that snakes are dangerous, especially to mice.

Oh, dear!

Can friendship survive gossip? Should friends stick together, no matter what? And what do friends do when a friend is in trouble? Or when a friend has hurt feelings?

Do you know the answers? Mouse and Snake need your help!
