I'd want to be best friends with Spongebob. Spongebob likes to have a lot of fun, and that's just what I like to do. We would go jellyfishing, eat ice cream, and do all kinds of stuff! But of course he could get annoying, but I'd still like him. Oh, by the way, I didn't put Patrick as an option because he's kinda lazy, but if you'd want to be his best friend, go ahead and say so. No one's stopping you!
