The 130-Story Treehouse: Laser Eyes and Annoying Flies (The Treehouse Book, Volume 10)

Andy and Terry live in a 130-story treehouse. (It used to be a 117-story treehouse, but they added another 13 stories.) It has a soap bubble blaster, a time-wasting level, a 13-story igloo, the GRABINATOR (it can grab anything from anywhere at any time), a toilet paper factory, and an extraterrestrial observation centre for observing aliens.

As it turns out, though, it’s Andy, Terry and Jill who are being observed - and then abducted - by a giant flying eyeball from outer space! At first they're excited to be going on an intergalactic space adventure, but when they arrive on Planet Eyeballia, they discover it's not at all a friendly place. Will the gang be able to escape and get back to Earth and write their book before time runs out?
