Smidge is used to Karlsson, the funny little man with a propeller on his back, living on the roof. They are firm friends. Now, anytime Karlsson pops in, Smidge knows that there's fun and adventure in store. In this collection of stories, they gobble cream buns, do their very best to frighten the new housekeeper and almost become television stars!
