Old Tom - Season 1 Episode 46 Zoo-Loose

Angela and Old Tom are planning to go to the zoo, but the car breaks down. As Angela tries to fix it, Old Tom is accidentally picked up by a garbage truck and deposited at the zoo. There he has adventures in a lion's cage, has tea with the chimps and escapes from two attendants. When he hides in a rubbish bin, he is picked up by a garbage truck again and deposited back home. Angela hasn't noticed he was missing and, now the car is fixed, they drive off to the zoo. To Angela's surprise, all the animals seem to treat Old Tom like an old friend.
