Mud Alien (Samurai Jack)

This is an unnamed species of sludge-like entities which were allowed to depart from their world to Earth by the demon Aku during his reign of tyranny.

Biology
Members of this species appear to be made entirely of mud and possess yellowish eyes.

History
A group of individuals of this species made a totem in Aku's likeness out of sludge as tribute before him telling them to leave. Without Aku's tyranny, this race may never had transferred to Earth.
