Doctor Crayons

Doctor Crayons is a reccuring (and at times, main ) character in the popular spinoff Cult of Squid, first appearing in the episode The Cold War.

Description
Doctor Crayons first appeared in the episode The Cold War where he helped cure the cult of their sickness and took care of Brother Squidward. He then re-appeared in The Mixup where he was thrown into the cage.

He was only meant to be a one-off character, but the creator kept him around to experiment with him and as a result, he became one of his favorite characters to write.

Until the episode Canned Bread, he didn't have an official name, just "doctor." He was called Doctor Crayons for the first time in the episode
