What oc characters you have for Spongebob Squarepants? I have some of them. Here is an example
Greybob: He is a greyscaled Spongebob with black eyes. He is basically the opposite of Spongebob as he is more evil. He is more of a demon than a Spongebob character. He has the ability to rip his own face off revealing a more terrifying face. Human like teeth and eyes. His origins are currently unknown.
I'm sorry if this character does not sound kid friendly, but sometimes people make strange oc's based off something kid friendly. What oc characters you have?
