Adapted from Andy Griffiths’ and Terry Denton’s phenomenally successful Treehouse book series, Richard Tulloch’s play — The 13-Storey Treehouse — is action-packed, full of laughs…with a see-through swimming pool, a tank full of man-eating sharks and a lemonade fountain! Imagine living in a 13-storey treehouse that includes a secret underground laboratory, self-making beds, a vegetable vaporiser and a marshmallow machine that shoots marshmallows into your mouth? Well Andy and Terry are lucky enough to live in one, where they have a series of completely mad adventures. And today Andy and Terry manage to get their dates all mixed up. They thought that they were going to rehearse their new play, The 13-Storey Treehouse, except they forgot to write it! And to make matters worse, they need to find flying cats, a mermaid, a sea monster, an invasion of monkeys, and a giant gorilla! Despite not having any of these things, they do have a box of costumes and props, some pretty awesome technology and friends to help out!
