Fly pretends to be her superhero alter-ego - Fly Girl - and goes on a mission to rescue a Dung Beetle's run away home and newborn larvae. It's too big of a job for one super bug so she joins with her friends to form a superhero team to save the day.

When Lucas captures Worm, Mama Worm and a few other bugs, Fly, Spider and Firefly launch a rescue mission into the house to save their friends.
