They are not to play with them on the bus or at home. While Junie B. and her bestest friend Grace were riding the bus home it was all Junie B could do not to peek at it. She tried to convince Grace that one little peek wouldn't soil the material. Grace would have none of this. When Junie B gets home with the box she has to show it off to her grandmother and while she is twirling around and around her mother comes home and tells Junie B she had better take it off before she soils it.
Mother puts the box with the cap and gown in it on top of the 'frigerator.
The next morning Grandpa Frank Miller came to baby-sit. After talking Grandpa into getting the box down and giving it to her Junie B. goes to her room with the cap and gown to show her stuffed animal friends. Of course, Junie B. has to model it for her stuffed friends. She ran around and around her room looking for a cloth. She quickly took off the gown and soaked up all the driblets.
