Sludges are a type of alien blob shapeshifters. It is revealed that they tried to cause trouble on Earth and had been fighting The Plumbers.

Appearances in the Series
Max Tennyson's nephew, Joel Tennyson (whos family are all plumbers) fell in love with a female Sludgepuppy, (Possibly Puttys speiceis.) named Camille Mann, who appears in this episode in human form. Joel was about to get married to his alien girlfriend, but her family objected to her marrying a human. During the rehearsal dinner, Camille's ex-boyfriend disrupted the reception to forstall suspicion upon the parents, but he was quickly dealt with by Ben as Diamondhead. During the wedding the Mann family of Sludges and another Sludge (disguised as a wedding staff member) interrupted it, destroying everything. Ben turned into Heatblast to face the Manns, but later in the fight they merged into one being. The Sludges captured and engulfed Ben, dragging him into their body. They thought they had won, but then their insides boiled as Heatblast fired up and they started to dry up from the inside out. Heatblast exploded from the charred remains, and the Sludges were just a dried up statue. Joel & Camille finally got married, which put an end to the decades long Plumber/Sludge feud.

Weaknesses
Sludges can be killed by water, fire or by scattering enough of their body matter to the point where they cannot reconstitute (i.e. when Max set a Plumber gun to overload and stuck it in the body of one of the Sludges where it exploded).

Other Features
A female has two moving whiskers on their cheeks and two antennae (or eyebrows) above their eyes; Males don't have any of either. They are capable of taking on humanoid shape and features (such as skin and hair) or, in Camille's case, humanoid shape while retaining a mud-like appearance.

They can also transform their hands into deadly weapons, such as a spiked mace.

Plumber/Sludge Feud
The Earth's Plumbers & the Sludges were involved in a decades long feud, before it was ended by the marriage of Plumber Joel Tennyson & sludge Camille Mann.
