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.
