The prank war is on at the Jersey Shore house!

On Thursday's all-new episode, Vinny Guadagnino, Deena Cortese and Nicole "Snooki" Polizzi try to one-up each other in a practical joke war that leaves Guadagnino with a face full of cake after a food fight.

So how does Guadagnino strike back?

"I [took] Snooki's most prized possession -- the [stuffed] crocodile she sleeps with every night," he says in an exclusive sneak peek from Thursday's show.

While Snooki is out of sight, her roomie hoists the crocodile over the Seaside Heights, N.J. house they share and hangs him by a rope.

Watch the clip above for more of the cast's wacky antics and see the full episode of Jersey Shore Thursday at 10 p.m. (EST) on MTV.
