The Elephant's Trump (GUNK Aliens)
By Jonny Moon.
Description
Just when you thought it couldn't get any grosser Ugh! Who did that? Jack, Oscar, Ruby, and their robot dog Snivel have defeated one of the GUNK aliens, but there are still three more to be captured. And that's bad news when the alien you're looking for likes nothing more than the smell of farts. - from Amzon
