|First Appearance||Big Fat Alien Wedding|
Lenopans, usually referred to as Sludgepuppies or 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.
Female Lenopans have two mobile whiskers on their cheeks and two antennae above their much larger eyes, while males lack both. Male Lenopans usually have smaller eyes than females.
BackgroundJoel Tennyson and Lenopan Camille Mann.
In Big Fat Alien Wedding, 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 forestall suspicion upon the parents, but he was quickly dealt with by Ben as Diamondhead.
During the wedding, the Mann family and another Lenopan 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 Lenopans captured and engulfed Ben, dragging him into their body. They thought they had won, but were defeated from the inside by Heatblast's heat, which dried and solidified them into a brittle mass. Joel and Camille finally got married, which put an end to the decades-long Plumber/Lenopan feud once and for all.
Roughly six years later, Lucy Mann became the first Lenopan Plumber.
Powers and Abilities
Lenopans can stretch, morph and shape shift their bodies in any way shape or form at will, as well as changing their color and texture. If they stretch too far, it might result in the part falling off. They can detach their body parts, and stick them back on, reattaching them. If they are disembodied, their pieces will instinctively come together again and reconstitute them.
Lenopans can shapeshift their body parts, and sometimes themselves into other objects. Using their sludge, they can look like another shape made of purple sludge, while they can still move while in liquid form. Their ability to mimic color and texture allow them to mimic flesh or fabric exactly. They can also shapeshift into non-existent or imaginary species complete with unique abilities. They even can morph their body parts into melee weapons.
Their liquid bodies can also be gelatinous, to the point where they are like large masses of muscle tissue, allowing them to be tangible and giving them the ability to physically interact and be mobile. Their bodies also generate slime, resulting in person jump through them, only to be covered with it, them being able to fire sticky sludge to subdue a target like webbing, and them being capable of regeneration and growing back parts of their bodies.
Lenopans can be harmed by water, fire, or by scattering enough of their body matter to the point where they cannot reconstitute (e.g. when Max set a Plumber gun to overload and stuck it in the body of the Bodyguard where it exploded). They will dissolve in water and turn the water purple, as they are unable to change out of liquid form, and fire will cause them to turn into brittle statues. However, both of these methods will only neutralize them and are not lethal.

Naming and Translations
|Hungarian||Iszapfráter||From iszap, sludge and fráter, critter|
|Spanish (HA)|| Desperdicios (Ben 10)|
Novatos de lodo (Ben 10: Omniverse)
| From desperdicios, wastes|
From Novatos de lodo, sludge rookies
|Spanish (Spain)||Cachorros de lodo||From cachorros de lodo, sludgepuppies|
- According to Deefus, Sludgepuppy is an offensive racial slur, and the proper term is Lenopans, though no other known Sludgepuppy seen has had a problem with the term until Deefus made his dislike of it known in Omniverse.
