A powerful humanoid mammal capable of brining positivity to any situation. With a tremendous amount of strength, the Kostro can survive a month on a single sip of water. The Kostro is also the only animal which appears above the Great White Shark on the food chain, though it presents no threat because of the dual level of respect. The Kostro can often be found shirtless, with a beer in hand, and a smiling face.
That rocket wouldn't have needed fuel to get to the moon if it was a Kostro.
