Mega Grow Creatures is a fun activity toy. Watch this marine animal grow much larger than before! This awesome super creature will keep your kid on their toes as they watch the item grow larger and larger day by day until it reaches its full growth potential. Imagine your child eagerly waiting and studying the growth of animals over a period of days. All you need is water and it will magically grow! Pull the animal out of the cool water and watch as it slowly shrinks back down to original size so that you can watch it grow all over again. Creatures grow up to 600% of its original size, just soak in water. Mega Grow Creatures come in a variety of fun styles including Alligator, Lobster, Crab, Octopus, Starfish, and Sea Turtle!
