The Grow Sloth water-grow toy is one of Toysmith’s popular water-grow toys for party favors, birthday gifts, and in-classroom use. Each tree-themed package contains 1 brown tree stump and a squishy sloth inside. Submerge the tree stump in water for 48-72 hours and watch as the stump slowly dissolves away to reveal the tiny sloth inside. Once the sloth appears, remove the tree stump, replace the water, and allow 3-10 days for it to finish growing.
