Pink Ninja 

Pink Ninjas are stealthy, and strike without warning. They are experts at concealment, until they become overly excited. Typically 5 1/2 - 6 inches tall and with prominent veins, they are accompanied by their two faithful hairy companions.

Alternatively, another name for the penis.

The pink ninja slipped into the bushy undergrowth.
