List of Characters by Appearances

This is a list of appearances of the ten casual characters in the show. Plankton, Karen, SpongeBob, and Mr.Krabs have appeared in every episode.

'''NOTE: This is a list of APPEARANCES, NOT A LIST OF CHARACTERS WHO ARE IN TRANSCRIPT EPISODES. (ex. In the Krusty Krab scene in "Kiss The Box", Squidward is shown but has never spoken a line.) In the same topic, Squidward made 12 appearances but has only spoken in four.'''
