Where have we seen this lovably lumpy, ceaselessly sniffling, endearingly dorky boy before? Although Sheen can't seem to put his finger on it, Doppy is obviously Planet Zeenu's very own version of his good friend Carl Weezer! He is also the only creature on Zeenu who's more of an airhead than our hero, Sheen. This, of course, makes them fast friends. And although the royally rude Dorkus is always trying to trick Doppy into betraying his new bud, the four-eyed, sluggish sweetheart always does his best to help Sheen succeed.
