Role in series

SpongeBob SquarePants

"SpongeBob's Big Birthday Blowout"

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.

"There Will Be Grease"

He is part of the crowd watching Mr. Krabs and Plankton sing "Everything Juice," where he asks if Everything Juice will make his voice sound creepier, to which Mr. Krabs responds "probably."

The Patrick Star Show

"Bummer Jobs"

He is one of the viewers of The Patrick Show!, where he is amazed at Patrick's tie-tying antics. Patrick then falls out of his TV and lands on him during his struggle, causing Slappy Laszlo to admire the 3D effects of the show.

"Stair Wars"

He appears among the crowd who comes to assist Patrick and GrandPat in their stair war, taking Patrick's side in those who wish to go up the stairs. He steals Fred's bread weapon, slathers butter on it, and then slathers butter on Fred's face.

"Lost in Couch"

He appears outside of the window of Patrick's house after Squidina tells Patrick his fan-base is counting on him. He tells them to not mind him and that he "loves a good failure". At the end of the episode, he is disappointed when everything works out.


He is one of the four characters Patrick has answer phone calls (along with Squidward, a worm, and a can of beans). At the end of the episode, he rides the dangerous obstacle course intended for GrandPat with Patrick.

"Terror at 20,000 Leagues"

He is in the crowd of The Patrick Show! and wears a fruit headdress, red top and skirt, and white beaded necklace as a Halloween costume. He gives a kid in the crowd broccoli as a treat.

"Pearl Wants to Be a Star"

He shows up whenever Pearl messes up her act for The Patrick Show the last two times, saying that it at least ended tragically, and that it had a catastrophic ending.


  • He is a caricature of the actor Peter Lorre, who was also caricatured in many Looney Tunes and Merrie Melodies throughout the 1930s to the 50s.
    • The fact that he is renamed Laszlo in The Patrick Star Show further proves this, as Peter's birth name was László Löwenstein.
