You may see the Spongebob cel above as my profile picture. This is the deleted scene from the episode "Texas", but Spongebob appears to be in the Krusty Krab.
Now before you call me an idiot, yes, this could be a prototype background for the deleted scene, but I do not remember a scene of the Krusty Krab with open doors and Squidward next to a table.
What intrigues me is that this might be a planned scene where Spongebob actually made it to the Krusty Krab during the chase scene.
