Betty's young cousin, Buzzy, takes the train to visit Betty. On the train, she's helpful, in a bratty kind of way, using her chewing gum to stick on a sleeping man's toupee, watering the flowers in a lady's hat, etc. At Betty's house, she sees the boys next door playing marbles and tries to join in; she proves better at things like walking on a fence than the boys, and even fares well with the goat the boys unleash.
