Character Appearances

Major: An appearance that is huge, obviously.

Minor: A small role in the episode.

Supporting: That weird mix between a major role and a minor role. It could also mean the character is just there but doesn't really do much. Also, it could mean the character was there to help the others.

Cameo: When the character only appears briefly or has really nothing to do with the plot.

This list does not include times when the character is MENTIONED or has briefly SPOKEN, only when they actually APPEARED on screen.

SpongeBob SquarePants
He has appeared in every episode except The Algae's Always Greener, no point to put a chart here.

Squidward Tentacles
Squidward will not have a chart. He, SpongeBob and Gary appear too often to need a chart.

Gary
Gary has appeared almost as much as SpongeBob, so a chart is not necessary.
