Judy is upset and jealous that Stink and their parents get to go on a field trip to the White House while she has to stay at home and finish her collage. She is also stressed that she has three gaps in her collage and cannot think of how to fill them. To make matters worse, it is Tooth Brushing week at school, and Judy finds the mascots, Floss and Tooth, boring.

Stink is dressed up like the American flag, and he and Judy bicker about his costume. Judy decides that Frank’s party is no longer the worst thing ever—missing out on the White House is.

Judy has a bad day at school. She gets wet in the rain, misses a word on the spelling test, and is picked to act out a cavity at the school assembly. The whole day she was distracted, thinking about all the adventures on which she was missing out.

After school, Judy goes to the shop with Frank and Rocky and buys a fake human hand. She has no idea what to do with it; she just finds it strange and funny. The children go to Rocky’s house, where they see his finished collage.
