Jack’s got a job selling popcorn at the Bonzo Boon Hippo Circus but Bonzo’s had an accident with a hippo and the Moose is on hand to seize the moment. The show needs a new star (the Moose) he says, and a clown (Jack). The crowd loves Moose and Jack but when the irritable hippos arrive, the Moose is off up a rope ladder fast.
