Acting like an Earthling isn’t easy! Follow the adventures of Spork the alien in the How to Be an Earthling series. Each book covers a different character trait to help kids think about what they say and do.    Cosmic! Finally Spork has earned his Solo Explorer Badge! He just needs to fly back to his planet to get it. Thanks to Gloop, his wrecked spaceship is as good as new. But the tank is empty— he’s out of truzzle juice! Refilling it is too big a job for one little alien . . . but luckily, Spork’s not alone! Every How to Be an Earthling title includes fun back-of-book activities that build on story themes.
