Ep 44. Zero the Penguin comes to visit

Maria does some work in Fix-It Shop, when in walks Zero, a penguin cousin of Big Bird's. He's come to visit all the way from the South Pole. Maria spots Big Bird coming over and proposes that Zero hide and surprise him (despite the store being too hot for him). Big Bird struggles to put together the clues, while Zero boils from behind the worktable. He finally reveals himself and rushes outside where it's cold.
