I was watching Spongebob Squarepants and one of the episodes I saw had a guest appearence by the rock band Pantera and when I watched it I never realized that Spongebob Squarepants was a favorite cartoon of many celebrities that they get to provide guest voices of characters. Another episode I saw of Spongebob Squarepants had Gene Simmons voice a character on the series. Is Spongebob Squarepants a favorite cartoon of many celebrities and because of this does Spongebob Squarepants do lots of episodes that feature celebrity guest voices?
Bestie

Yes.

They've been doing that in more recent seasons. The earlier years kept the guest stars to a minimum.

Hi Bestie! Here is a list of celebrities that did voices on Spongebob Squarepanrs. Hope it helps. It might look funny but that is how it came out.
