User blog comment:Luks7/BETA HAT REFERENCE IN SPONGEBOB SHORT!!/@comment-4500149-20130228022127

Oh yeah, I remember noticing the same thing in the episode where they get shocked by an electric fence. :P However, I doubt it's a direct reference to Club Penguin. That's like saying whenever you see a pink and yellow party hat anywhere outside Club Penguin, it's automatically a reference to it. It's just a coincidence.
