Role in series

The SpongeBob SquarePants Movie

SpongeBob and Patrick have to cross this area where these monsters live, and the creatures and beasts are not a threat, since they believe they are "invincible" and nothing can hurt them, seeing how Princess Mindy gave them "mermaid magic," turning them into men. These monsters really want to eat them, until they go along with the song and become their friends, only to be turned down after the "men" call them hideous and disgusting.

"A Life in a Day"

Patrick attempts to jump over them on a skateboard.

"The Night Patty"

Smaller versions of them visit the Krusty Krab during the night shift.

Grandma's Cookies

They appear as an obstacle.


  • Most of them are based on real deep-sea creatures, such as the anglerfish and humboldt squid.
  • The monster making the yelping sounds at the stairs is not actually seen.
  • The light on the road-like monster is designed to look like a traffic light.
  • In the movie, the monsters are huge, but in "The Night Patty" they are about the same size as SpongeBob.
