 The boys buy mama a new hat for Mother s Day, but on the way home, fall in the mud and ruin it. They swap the bad hat with one that a nearby horse is wearing and head home, with the horse in pursuit. Mama loves her new hat, and sets out to show her friends, but encounters the horse, who goes after the hat. The horse chases her home, where the kids divert it into a room and try on several different hats. The horse tires of this, and ends up in the basement, where a gluepot spills, attaching a fan to its rump, which gets switched on and, combined with a drop-leaf table, turns the horse into an airplane. It collects the entire family, flies outside, and eventually crashes into a circular clothes rack, which turns into a merry-go-round with everyone grabbing for the hat like a brass ring.
