Sylvester

The Sylvester is one of the Aliens that is encountered in the Insaniquarium Universe. It is one of the first Aliens encountered in the game, and is also one of the weakest.

Sylvesters hold some physical resemblance to the Xenomorphs in the upper body, their lower bodies ending in a pointed slither tail. It also doesn't have any eyes, but still able to sense the world around it. They're primarily fish eaters.
