Pirates Love Underpants follows a crew of pirates on a quest to find the fabled Pants of Gold for their captain's treasure chest. The journey takes them across a series of vividly named locations — Long-John Bridge, Big Knickers Bay, and Three Pants Ridge — encountering crocodiles, sharks, and assorted obstacles along the way. The production combines music, puppetry, and visual spectacle to bring the adventure to life for young audiences.

Based on the children's book by Claire Freedman and Ben Cort, the stage adaptation is suitable for children aged one and above.
