If you want a charging station for batteries, you either find one or put a battery into these guys. Try to trap a bunch of them in a enclosure and you will have a charging station next to your base. A substitute choice, just make a base next to a charging station
Capable of being pinned down by a raptor for an easier kill since once you hit them they scatter rather quickly. Good animal for early game, loses out to crabs (chitin) and charge stations (batteries) late game.
