A hole in the roof means rain water is leaking in through the ceiling of Topsy and Tim's bedroom, making Topsy's top bunk and Little Moon Bunny wet. Tim helps Dad mend the leak with some help from Kerry's dad, Carson.

Topsy and Tim can't sleep in the bunk beds as usual because their bedroom is being redecorated by DIY Derek. The twins look for somewhere else to sleep until Dad tells them they're going on a special camping adventure.

When Topsy and Tim's friends Tony Welch and Vinda come to play, things don't quite go to plan at first but by the time their mums come to pick them up, the friends are having so much fun they don't want to go home.

Topsy and Tim are growing out of their old, matching twin clothes, so Mummy buys them new jeans. Topsy is delighted with her new jeans - they have butterfly designs all over them. Tim's new jeans have a cool dinosaur print but Tim is not sure he is ready to wear bigger clothes yet, especially ones which are completely different to his twin's.

Grandma and Mossy the dog have visited Topsy and Tim but when it's time to take them home for Mossy's tea, Dad simply cannot find his house keys anywhere.
