Spongebob: [Cut to SpongeBob running in the halls and into the bathroom. He hides in one of the toilets] What am I gonna do? [hears the door open] What was that?! Someone’s coming! They’re getting closer! I’ve just gotta act natural! [fish opens the lid and sees a kitchen sponge floating in the bowl]

Fish: Oh that’s real nice.... [walks out]

Wasn't Flats the one who said he was going to beat Spongebob up?...for various reasons some I found to be sillier than others...Squiddy can be a little hostile towards Spongbob but that's only because he wants to be alone and for other reasons.

Flats is REALLY insane. He's evil and he knows it.
