There is something odd about Sara and Michael Buckner's new home. It's not just the weird old gargoyles, the creaky floorboards, and odd noises at night. As Sara and Michael are about to find out, terror awaits just beyond the doorstep of Moonlight Mansion. From the creators of the bestselling Goosebumps series comes a new series to thrill middle-grade readers. Includes temporary tattoo.

Michael and Sara are beginning to notice eggs all over the house—strange purple eggs—and it's not even Easter. Then horrible half-insect, half-rodent creatures hatch from the eggs. They're creepy—they're crawly—and they're multiplying fast! Can Sara and Michael get rid of the creatures . . . before the creatures get rid of them?

All sorts of weird things start to happen when Aunt Wendy arrives at Moonlight Mansion. Sara and Michael's long-lost aunt is certainly strange - so strange, the children nickname her Aunt Weird.

Hating the gruesome gargoyle that is perched atop Moonlight Mansion, Michael becomes certain the gargoyle is bad news when it falls off the roof and narrowly misses him, and soon realizes that the statue is trying to change places with him.
