The first one isn't possible, but If you want me to answer the second one, I'd have to check all the episodes, and the backgrounds could take a while. But I'd say that those are both questions that I can't answer from memorry, so you've stumped me, and you always will on that kind of question. I don't know everything about SpongeBob you know.
And Hannah, I'm not going to tommorow, but a week from tommorow I hopefully will go.
