 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.
