Whisper Ooze

From Introduction: What you first took for a puddle of dirty water, suddenly rises like a snake and lunges forward. All sound ceases as the slithering puddle of goo approaches. A whisper ooze is a mindless predator that is attracted to loud noises. When at rest, a whisper ooze is almost indistinguishable from a puddle of dirty water. A whisper ooze can grow to a diameter of up to 10 feet and a thickness of about 6 inches. A typical specimen weighs about 700 pounds.
