Sludge

Sludges are Titans that are more poisonous and revolting than Stenches.

The Sludge was created by Dr. Neo Cortex but was used by Nina Cortex in Crash of the Titans. It is a mutated toxic sludge that specializes its slime for attacks; it can extend or expand its arms to attack its foe. Its slimy body also gives it the ability to shapeshift; it can sink into the ground and form a slug like form and then come up from behind and punch the enemy with an uppercut. It also vomits a highly venomous acid that poisons Crash and other foes; when a Titan gets poisoned by Sludge's toxic venom, the Titan will be engulfed by a toxic green gas signifying it was poisoned. When Crash attacks the poisoned Titan, the Titan will be instantly stunned. In Mind Over Mutant there are some non-mutated Sludges living in the Junkyard.
