"If you want to pretend you're shrinking, that's all right," said Treehorn's mother, "as long as you don't do it at the table."
But Treehorn wasn’t pretending. He really was shrinking, and that didn’t make life easy for him as he became smaller by the moment.
Treehorn’s teacher said, “we don’t shrink in this class,” and sent him to the Principal. Poor Treehorn spends an unhappy day and night until he discovers a magical game that helps him solve his problem.
