Ok, don't worry, this is probably not the last episode of Spongebob, but the last episode of season 9. "Factory Fresh". The episode that was being promoted by "Goodbye Krabby Patty". The 200th episode of spongebob, ends it? I want you to search up "factory fresh promos" until you can answer.
Edit: please check my topic "Godbye Krabby Patty Projects" to find where you can code stuff to get it out there.
