The Tweenies start the day with some painting. Fizz thinks it would be a good idea to paint rainbows but Bella decides that the only colour for her is red, and so she creates a club where everything has to be red. Jake joins the Red Club but Milo and Fizz decide that they also like many other colours, so they stay in the playroom to finish their rainbows. Bella and Jake manage to find many red things to play with but eventually they realise that their rules are too strict.
