S1·E2 Pingu Helps to Deliver the Mail

Pingu is helping his dad deliver the mail. His dad lets him wear his postman's hat, and they go to the post office to pick up the mail and then deliver it to the town's various eccentric residents; including an old, kid-hating granny penguin, a tall, loud-beaked (bird style for loud-mouthed) penguin, a short, zippy and strange penguin in suspenders (this is Punki, who also slams the door right in Pingu's face as he opens it!), Pingu's friend Pingo, a sad penguin with bad news, a woman with three children, and others, before returning home again to his mum's arms.
