The Big S.T.A.N.K.After getting a splinter in his rear from sitting on his throne, Julien wishes to replace it with a new one. Meanwhile, at the penguins' HQ, Rico accidentally brings a long-hidden project, S.T.A.N.K., into view. S.T.A.N.K., a stink bomb-armed toilet once intended to trap Dr. Blowhole, was abandoned after the penguins discovered that dolphins do not use toilets. To now permanently get rid of it, the penguins decide to transport it to a highway rest stop. But Julien, desiring it for his new throne, pursues with Maurice and Mort and subsequently gets himself strapped to the S.T.A.N.K. upon sitting on it. With the S.T.A.N.K.'s core approaching meltdown, Kowalski and Maurice return to the zoo to try to figure out how to safely free Julien without the bomb detonating. It is ultimately determined that sodium chloride will short out the lock on the restraints, and that tears would be an effective solution. After Julien is unable to cry on command, Skipper thinks of all the time he had wasted with Julien and sheds a single tear, unlocking the restraints just before the S.T.A.N.K. explodes.
