The ants in Lucas's yard are tired of being bullied by Lucas and his water gun. So they devise a way to get back at Lucas - they use a magical potion to shrink him down to the size of an ant! The Queen tells Lucas he must prove himself to the colony by learning their ways before she will allow him to return to his real size - and to his family. Will Lucas be able to prove himself to the ant colony, or will he spend the rest of his days trapped in a body the size of an ant?
