Until you learn how to spell sequel, I don't think you should make a spin-off at all.

Personally I think Rocky's idea is really good, but what about a series where SpongeBob feels like his optimism gets in the way of his true happiness and has an existential crisis, eventually leaving Bikini Bottom and trying to get a grip on his life and personality before he can't handle it anymore.
