Role in episode

He first appears in the line for SpongeBob's surprise party, where he creeps out Larry the Lobster by talking about cake while rubbing his stomach. He is later seen sitting on a table against Sandy's orders, where he swallows an entire cake whole and breaks the table in half. Soon after, he shouts "surprise," causing a riled up Sandy to punch him.


  • He is a parody of the actor Peter Lorre, who was also caricatured in many Looney Tunes and Merrie Melodies throughout the 1930s to the 50s.
  • His name and attire are a reference to Slappy the Dummy from Goosebumps.
