280B Sounds very weird280a. Abandon Twits: The Krusty Krew builds a boat for their penny-pinching captain.
280b. Wallaha: SpongeBob discovers a crazed castaway living in his walls.
Interesting plots.
One thing I will say is that, at the very least, these plots sound like original concepts for the show (yeah I know, we've reached a point where that's a unique feature).
