The 13-Storey Treehouse

The 13-Storey Treehouse is a 2011 book written by author Andy Griffiths and illustrated by Terry Denton, and a stage play based on the book. The story follows Andy and Terry, who are living in a 13-storey treehouse, struggling to finish their book on time among many distractions and their friend Jill, who lives in a house full of animals and often visits them. According to the book, the 13-storey treehouse has "a bowling alley, a see-through swimming pool, a tank full of man-eating sharks, a secret underground laboratory, a vegetable vaporizer and a marshmallow machine that shoots marshmallows into your mouths when it sees that you are hungry". The 13-Storey Treehouse won the Australian Book Industry Awards Book of the Year for Older Children 2012 and the 2012 COOL Award for Fiction for Older Readers.
