Sea-Monkey Magic Castle
by Sea Monkeys
Enjoy observing the life cycle of Sea-Monkeys, a unique species of brine shrimp as they live and play in a miniature castle.
Sea-Monkeys grow up to 3/4" long and live up to a year or more! They even produce babies, and you can "teach" them to do tricks. Sea-Monkeys will hatch almost instantly, usually within a few hours of adding them to water!
This complete Sea-Monkey kit includes a mini-tank with built-in magnifiers, Sea-Monkey eggs, water purifier, growth food, and complete instructions. Sea-Monkeys are guaranteed by the manufacturer to grow.
