The only way I found this one in a cave, during the day, was that I saw a random medium sized poop. Basically everything in the caves drops small poops so if you see a medium, look for the mega close by. I must have ran by her like 5 times before I realized it was not just a rock lol. The knock-out and tame was easy with 5x taming on my server. Getting her home during was the tricky part.
