Mouse calls her friend Elephant to see if he can play. But he doesn't feel at all well. He may EVEN have . . . the dreaded ZOO FLU! So Mouse calls their friend Giraffe to tell her about Elephant. Giraffe calls another friend who calls another. But something is wrong with the phones and it's hard to hear what is said. Soon each of Elephant's friends hears something VERY different about what is going on with him . . . and maybe . . . just maybe, it isn't the ZOO FLU after all!
