SpongeBob

SpongeBob is a lead singer of his own band. Like other Animatronics, normal during the day and an insane murderer during the night.

Appearance
SpongeBob is a yellow kitchen sponge who has no holes. SpongeBob has blue eyes, buck teeth and a long nose. SpongeBob wears a lavender shirt with grey pants. He is the only animatronic who wears shoes after the socks. He is seemly holding a microphone.

Locations
Unlike his occupation, he starts at the Kitchen. It's unclear why a lead singer starts in a kitchen rather than start on the stage(maybe he is up for a midnight snack).

When he leaves the kitchen, he may go to the Mascot Only Room, Bathrooms, Hallway and the Dining Area. He won't appear anywhere else.

A very strange thing happens to him, is when he left The Office's blind spot after being locked outside when the doors are closed, he actually return back to the kitchen. It's unknown why this occurs.

Behavior
Unlike any other animatronics, SpongeBob returns the Kitchen once he leaves the office. This can assume that he doesn't really hand down the whole murderer thing.

SpongeBob was named as the cutest animatronic in the whole series, even he doesn't have eyebrows at all. SpongeBob is popular because he is yellow, he has big cute blue eyes, or maybe he looked like a plushie more than a killer.

SpongeBob can attack the player when he is outside the opened right door. He cannot get in the office unless the Monitor is up, similar to Patrick and Mordecai. SpongeBob has no ability like Mordecai that can be seen with the Flashlight after snuck in. After all, when the monitor was down after he snuck in, he screams the player immediately, which is the opposite of Piglet, who attack randomly after he had snuck in.
