The Junkman's species

The Junkman's species is a sapient, spacefaring unnamed species of four-armed humanoids.

Biology
These creatures physically resemble a Yautja, although their mouths are more human-like, and they have an extra set of arms, and eyes in the back of their heads, and tridactyl hands.

Notable members
A notable member of this species is the interstellar garbage salesman known only as the Junkman, a mean, greedy, evil and sociopathic individual who literally sold his own mother just for a quick buck. And a few anonymous audience members of Intergalactic Showdown, one of which has a bionic eye.

History
This species was first encountered by boy genius Jimmy Neutron, when he and his friends were abducted by the Junkman.
