Andy and Terry live in a 65-Story Treehouse. (It used to be 52 stories, but they keep expanding.) It has a pet-grooming salon, a birthday room where it's always your birthday (even when it's not), a room full of exploding eyeballs, a lollipop shop, a quicksand pit, an ant farm, and a time machine...which is going to be really, really useful now, since Terry messed up (again) and the treehouse just FAILED it's safety inspection. Join Andy and Terry on a whirlwind trip through time as they try to stop the treehouse from being demolished!

Andy and Terry's incredible, ever-expanding treehouse has 13 new storeys, including a watermelon-smashing level, a wave machine, a life-size snakes and ladders game (with real ladders and real snakes), a rocket-powered carrot-launcher, a Ninja Snail Training Academy and a high-tech detective agency with all the latest high-tech detective technology, which is lucky because they have a BIG mystery to solve - where is Mr Big Nose???

Well, what are you waiting for? Come on up!

Who wouldn't want to live in a treehouse? Especially a 13-storey treehouse that has a bowling alley, a see-through swimming pool, a tank full of sharks, a library full of comics, a secret underground laboratory, a games room, self-making beds, vines you can swing on, a vegetable vaporiser and a marshmallow machine that follows you around and automatically shoots your favourite flavoured marshmallows into your mouth whenever it discerns you're hungry.

Two new characters – Andy and Terry – live here, make books together, and have a series of completely nutty adventures. Because: ANYTHING can happen in a 13-storey treehouse.

'That pencil is dangerous,' I said. 'Even when you draw something nice, something bad happens.'

When Henry McThrottle tells his fellow students at Northwest Southeast Central School that his pencil is trying to kill him they accuse him of having an overactive imagination. But if that's the case, then why is his pencil still trying to kill him?

"Mr Brainfright says: It's important to keep a sense of humour at all times, especially when you're being ripped apart by a lion.

Mr Brainfright is a teacher at Northwest Southeast Central School. He teaches Grade Five and in his class is a student called Henry McThrottle who likes telling stories. That's me. I'm Henry McThrottle and this is my latest story. It's about an evil pencil, a runaway lion, an avalanche and - falling out of windows. I hope you like it."

It doesn't take Henry McThrottle long to realise that Mr Brainfright, his new teacher at Northwest Southeast Central School, is rather unusual.

His last teacher would never have fallen out of the window twice- or taught Class 5C how to skid on banana peels.

But Henry's got even stranger things on his mind ...

On a trip to Principal Greenbeard's office, he discovers that there is buried treasure on Skull Island, which is somewhere in the school! Henry and his friends Jenny, Gretel, Newton and Jack set out to find a chest filled with gold, jewel-encrusted goblets and pieces of eight (whatever they are).

But soon their secret is out, and everyone has treasure fever.

Can they find the buried treasure, beat the bully, catch the villain and save their teacher, Mr Brainfright?
