It Came from Beneath the Sink! 

From the New York Times-bestselling Goosebumps series, two siblings discover a monster lurking beneath the sink of their new house that preys on bad luck. Kat and her brother, Daniel, are so lucky. They just moved to a new house with tons of rooms, two balconies, and a lawn the size of a football field. But all that good luck is about to run out. Because there’s something really evil living in their new house. Something that’s moving. Watching. Waiting. Something that comes from beneath the kitchen sink. It might look like an ordinary sponge. But this scary creature doesn’t do dishes. . . .
