I'm the supreme commander of the armed forces, can you tell me what you remember about the beings you captured? Where did you find them? What happened?

While scouting through the mountains, I heard weird gurgling noises. When I went to find the source of noises, I came upon those cages in a clearing. After finding out what they were, 3 Lennys showed up, and attacked me. I managed to kill them, but not before losing my left arm and getting shot.
