I can't for the love of god scan these Shriekbats. They're too fast, and I'm never able to fully scan them. I've missed them on the Crash Site and the Gateway area. After I acquired the Grappling Hook, and activated the ship's map, they disappeared.
Have I missed that scan for good? I can't find a spot where I can scan them without them dive-bombing me. The Crash Site room is impossible, and they don't respawn on the Gateway room.
Please help! Can I find these bastards anywhere else in Bryyo? I am not intending to restart this game over a missed scan.
