Your child can become one with the shadows (as if they're not hard enough to keep up with) in this hidden ninja warrior costume. The black jumpsuit is built for plenty of playtime action, and comes with a belt full of toy throwing stars and a hood to conceal your child's mysterious identity. (Even better, you can remind him while he's playing that stealthy ninjas work in complete silence.) Let him pick out his favorite cool ninja sword to go with.
