Submersion in water reveals the secrets hidden within these alien rocks!

Transforming Alien Rocks dissolve in water to reveal a one inch translucent miniature replica of an alien hidden inside. Don't take your eyes off the fizzing rocks; the changing colors are too cool to miss! The Transforming Alien Rocks can be played in the Alien Laboratory, the Battle Planet or on their own. This set includes two rocks featuring Kraab and Gwen.
