Desert Muck Leech

The Desert Muck Leech was a race of simplistic leech creatures living in a puddle on Mars, a puddle which was later paved over for a car park for the new Mars Vegas.

These Leeches are descendants of the Dark Ones, who fought in the Arms Race of Evolution but the only one survived the paving of the puddle that they lived in. This one would later kill Frida Waterfall and Hutch Waterfall, but itself would be killed by an Encyclopod.
