Tippey Lemmey is the new dog in town, and Leandra, Paul and Jeannie think he is a real monster. When they ride their bikes, he chases them, snapping at their heels. When they run, he runs. If they cross the street , he follows. They try to come up with a plan to stop Tippy Lemmey, but nothing works. When he finally does something totally unexpected, the kids realize that maybe he's not their enemy after all.
