Blast off into outer space and meet a wacky crew of extraterrestrials who do everything completely backward. You will travel across the galaxy to discover how these funny aliens demonstrate opposites in the most hilarious ways possible.

You get to pull the interactive tabs to watch the space creatures change sizes, switch directions, and show off their unique personalities. Every page gives you a new pair of opposite words to learn while you explore their bizarre alien world. Join the cosmic fun and see if you can guess which silly opposite these bizarre visitors will show you next.
