My friend nearly cried when he fought a Peco the other day. The Unstable Rathian wandered into the area and Peco called Jho... he's fairly new to the game, so it's safe to say that "terrified" is a poor term to apply.
When this happened to me, I tossed a dung bomb on the peco and killed the Rathian instead. got my carves and captured the peco a few minutes later. --- I used to think my brain was my favorite part of my body...Then I realized what was making me think that!
