Life is tough for Lenny. He's the short, skinny kid who gets pushed around by everyone. His mum still chooses his clothes and treats him like baby, whilst his older brother is the most popular boy in school.

Fed up with being overshadowed and bullied, Lenny decides to transform himself. He wants to be bigger and stronger. So he secretly begins eating nails and drinking engine oil, waiting for his legs to turn into wheels and his arms into pistons.
