From Toysmith’s popular Grow line of water-grow toys is the Toysmith Grow Unicorn. A popular water-grow toy, this pink and white unicorn with a gold spiraled horn emerges from a bright pink tree stump once submerged in water. Just drop it in water for 48-72 hours and watch the unicorn emerge! Each rainbow-themed package contains 1 pink tree stump and a squishy unicorn inside. Each unicorn emerges from the tree stump and then grows bigger in size as it soaks up the water. 12 unicorns can fit in the pink 7.09-inch x 8.66-inch display case.
