Sophie Mouse is painting in Clio's Clover patch on a beautiful spring day when she spots something unusual. It's a clover ... but it has four leaves! Four-leaf clovers are supposed to bring good luck, right? Sophie waits and waits for this good luck, but it seems like just the opposite is happening. She spills paint all over herself, she doesn't have any fun daydreams, and she forgets about an adventure she was supposed to go on with Hattie! Will Sophie ever be able to break this Clover Curse?
