After Mikey helps Cornchip Girl off the climbing frame after she gets stuck, the gang wonder how big he will be. Gretchen and Galileo conduct a test to find out how big everyone will be when they are older, and Mikey’s test says he will be 50 feet tall! The others find this cool and wonder what 50 foot Mikey could do, but Mikey isn’t so sure that being 50 feet tall will be that great.
