The small boy appeared in Unpack Your Adjectives. He was shown with the Tall Girl. The girl grows taller and the boy starts laughing at her. He shrinks till he is the size of a speck, and the girl grows till only her legs and sandals are seen. The boy then gets stomped on by the girl who has had enough of being laughed at.
