Grow A Cowboy

Howdy, partner! Bring a little Western magic to playtime with the Master Toys Grow A Cowboy water-expanding toy. This miniature classic starts small but packs a huge surprise. Simply drop your cowboy into a container of room-temperature water and watch him grow up to 600% of his original size over the next few days. It’s a fantastic, slow-growing science experiment that teaches patience and curiosity. Once he's reached his full size, take him out of the water to watch him shrink back down so the fun can start all over again.
