When Dean snaps at Brainfreeze that he's a total "tofu brain" for breaking Dean's beloved D-tab, Brainfreeze takes it to heart. He doesn't want to be a brainless drain on his friends, so he confides in Madge, who has just the solution he needs: a brain food super shake. Trouble is, the shake - whatever Madge has put in it - works just a little bit too well, and Brainfreeze drinks a little bit too much of it. So much, in fact, that he can't surf. The residents of Monster Beach miss their friend. But can they outsmart Brainfreeze to get him back the way he was?
