The tales of Peter Rabbit, Jeremy Fisher and Jemima Puddleduck have been told at firesides and bedsides for over a hundred years, and now they're being sung on stage.
You can see 'Where is Peter Rabbit' the musical at the Old Laundry Theatre, which is part of the World of Beatrix Potter Attraction in Bowness-on-Windermere.
It's all part of this year's celebrations of Beatrix Potter's 150th birthday.
The puppets have all been made specially for the show. The actors have to play the part while also manipulating the puppets, which are quite heavy, making it exhausting work.
Beatrix came to live in Hawkshead and has been synonymous with the Lake District ever since.
Her name and the countryside she fought to protect, setting up the National Trust to conserve the Lake District, draw millions of tourists to Cumbria every year.
Around 200,000 people visit the World of Beatrix Potter every year and it's hoped the musical will attract even more.
It can seat around 20,000 between now and September with three performances a day during the Summer holidays.
