Goop

Goop is a sentient piece of alien goo from the caves in Blood Gulch. It was harvested and adopted as a pet by Wade and Max after trapping Reece in the caves it came from on his first day in the canyon. Goop contributed greatly to Wade's scientific endeavors while preparing the canyon for the battle against the Wort Blarg Clan. However, after the battle, Goop had disappeared.
