Tripod Hopper

The Tripod Hopper is an alien enemy cut from Half-Life 2. It never went further than the concept stage and was therefore never scripted.

Depiction
This three-legged creature moves by hopping from point to point and tries to land on the victim's head. Some kind of fluid is supposed to come from its central "mouth", helping what it's planning to do with its victim (poison them or put them to sleep before parasiting/killing them). It was probably meant to be a Headcrab/Sacktick-like parasite. Its design is also very close to the Gonarch's.
