While attending a St. Patrick's Day parade, Mike, Matt, and the other young ants pursue a mischievous ant leprechaun convinced that he will bring them good luck.
The kids of Ant Hill do a play about their ancestors' first Thanksgiving when they hopped on the Mayflower and sailed across the Atlantic Ocean and made many new six-legged friends around a big harvest spread.
The ants are putting on a dance show, but one ant is being bossy. Kai-lan must teach them that everyone is happier when they get to make their own choices.
