Dive into the mysteries of the deep sea with the Aqua World Grow a Marine Creature set. Submerge it in water to witness your sea creature friend expand up to six times its size. Remove it from water, and it will shrink back down, allowing you to repeat the growth process. With six sea creature designs to collect and dimensions of 130mm in length, 40mm in width, and 20mm in height, this set offers an educational and imaginative journey through the ocean.
