Hydra's night vision was quite good, and he was able to make out a large form in the room. From what he could see of the shape, he calculated what spot would be the most difficult to defend. Rearing his tail up, he plunged the massive stinger on it's tip into the creature's back, the appendage secreting a numbing venom into the creature's body. As soon as the venom was injected, Hydra pulled his tail back as fast as possible, trying to beat out the creature's inevitable reaction.
