Baba Yellow is painting Rainbow and Baba Green is hard at work in the garden. Baba Pink and Baba Blue are arranging a surprise for later that day. Bobo White is curious - but Baba Pink asks him to go help Baba Green in the garden. Baba Green is watering his fluffygold flowers, and Bobo tries to help. Bobo hastily splashes water all over the garden and Skydonk. Baba Green explains to him that you need to do things nice and slowly in the garden. Baba Yellow is a little distracted from painting Rainbow's stripes - she is very excited about the surprise that Baba Pink and Baba Blue are planning. Much to Rainbow's distress, Baba Yellow hops on Yellowhorsey and flies off to give Baba Pink and Baba Blue some help with the surprise. Embarrassed that he's only been half painted and too impatient to wait for her to return, Rainbow attempts to paint himself, unaware of the mess he's making. Bobo arrives on Skydonk to find Rainbow with a blue moustache and splodges of paint all over him. Rainbow contorts himself to try and paint his back while Bobo offers to help. Bobo tickles Rainbow with his brush and in the commotion, the paint pots spill. Blue paint drops through the cloud and onto one of Baba Green's fluffygold flowers! When Baba Green turns round, he is very unhappy - blue fluffygolds just won't do!
