Lenopan

Lenopans, mostly called Sludgepuppies or simply Sludges, are a species of alien blob shapeshifters. Though now at peace with humanity, they have historically tried to cause trouble on Earth and had thus been in opposition with the Plumbers.

Appearance
Their natural conditions are legless and a vague human blob. Females of this race have antennas in their Sludgepuppy form.

Abilities
Lenopans have the ability to stretch their limbs and create their own weapons from their composite mud. They are impervious to Petrosapien Crystals.

Weaknesses
Being made a mud-like substances, makes them very weak if exposed to any amount of water in addition to fire.

History
The Lenopans hate the Plumbers, as there was a very long war against them. A Lenopan named Camille and a human named Joel fell in love, and when they got married, it possibly ended the war. The wedding tried to be stopped by a few sludges, but failed.
