Grow your own Galactic Space Terrarium! This collection of alien invader plants sprout antennas, turn into rocket ships, move when spoken to or touched, and were thought to have come from space by European explorers upon arriving to America. Create your own unique space scape with the included Glow in the Dark Asteroids, color decals and stakes. Add a lunar lagoon with Space Sand and watch water turn into Mercury! Finish the scene with your own alien landing. All the space specimens in this celestial set are quick to sprout and fast to grow.
