Crystal Hedgehog

This hedgehog has a big problem: it doesn't have any spines! And the only way it's ever going to get some? SCIENCE! Following the detailed instructions, young scientists simply mix the special solution into a container of boiling water and then set the poor, spineless hedgehog into the mixture. One day later and - (insert drum-roll) - Ta-da! Covering the hedgehog's entire back is a huge, spiky cluster of glimmering, colorful, sturdy, solid crystals! Experience the playful side of science with the Crystal Growing Hedgehog, available in five fun colors.
