Swimming Mouth Creature

The Swimming Mouth Creature is a briefly encountered major hazard in the Lethal Specimen Facility.

Description
This living barge of a mutant appears as a huge, upside-down mound-shaped creature with multiple eyes that follow Troy near the top, some of which are on stalks. The top is dominated by a colossal mouth with a tongue that can shoot out and grab Troy.

Behavior
The Floating Mouth will stay in the large pool of water(?) found after the first checkpoint in the Lethal Specimen Facility. It'll float directly underneath Troy as he tries to climb over the pool, and will shoot its tongue out to grab them if Troy's head gets too close. This isn't always fatal, and can be escaped.

Trivia

 * Its prehensile tongue, teeth color, and body color and shape bear similarity to the Pig Monster, mean that what it may.
