Aliens: An Owner's Guide by Jonathan Emmett
If you have made the brave decision to own your very own alien, then brace yourself for an experience that is out of this world!
This extra-terrestrial guide contains all you need to know about caring for your energetic, alien life form. With helpful hints and tips on how to pick the perfect egg and cope with cocoons and hazardous toilet habits (alien pee is acidic!). But watch out! Aliens are intelligent, they develop fast and may wish to return home. If you're not very careful, they may take you with them . . .
Another superbly funny spoof user guide with an intergalactic twist. From the creators of MONSTERS: AN OWNER'S GUIDE.
