The Booger From Outer Space (Scaredykids #1)
When Kermit, the new kid in school, gets infected by a green booger-like creature lurking beneath Harmony’s forest, Tor Bough isn’t too worried. But then Kermit starts acting really weird. For one thing, all he can think about is food and where to get more of it. And more. And more still. And for another, he can’t wait for Tor and his friends to get infected as well.
