The 13-Storey Treehouse (Treehouse #1)
This is Andy
This is Terry
They live in the world's coolest treehouse!
They've been doing some building work and now their treehouse has:
- It's got a tank of man-eating sharks!
- And a marshmallow machine that shoots marshmallows into your mouth whenever you're hungry!
- Just watch out for the giant mutant mermaid sea monster!
- And, whatever you do, don't get trapped in a burp-gas-filled bubble!
