Zombie Butts from Uranus (the planet)

I just read a book called "Zombie Butts from Uranus". And if you are
wondering, the Zombie Butts are from the planet: Uranus. There are a
lot of funny characters in it, but the basic idea is about a boy
named, Zach Freeman and, of course, his butt. They try to stop a
zombie butts from Uranus, because they were trying to take over the
world and they were indestructible. They gave off so much methane,
that 3 of the characters became immortal.

The most exciting part was when Zach got sucked into a black hole and
made it out alive. He was trapped with a girl who had methane
madness. She was singing all these nursery rhymes. Zach almost
thought of abandoning her, but he didn't. So, if you are looking for
a very, very, very funny book, that is disgusting and awesome at the
same time, read this one. by Cole Burgess
