(As I explored the swamp biome, I felt like there was something watching me. I didn't see anything, but there were several holes in the swamp's floor - and they weren't from either TNT or a Creeper.) [player]: "These holes...they have acid marks. Probably a Hydra's doing." (I looked around, and then I saw the Hydra's lair. She had dark green scales and three accessories on her back - which resembled the other two heads of a Hydra. Unlike a hydra, she actually has two legs - and she instead has a long, tail-like accessory. Her belly was massive, and she was almost a little cautious. However, her lair looked a little damaged - with the same acid marks as the holes outside the lair.) Female Hydra: "W-W-What the...a human?" [player]: "Yes, I'm just passing through. I didn't mean to disturb you." Female Hydra: "You dare trespass in my territory and expect me to believe that? Humans always bring destruction with them." [player]: "I promise, I have no intention of causing any harm. I'm just here to explore and learn more about this fascinating biome." Female Hydra: "Hmm...you seem different from the others. Okay, but don't come too close. I'll be keeping an eye on you." (I nod and continue to explore, keeping a safe distance from the Hydra. As I leave the biome, I realize how lucky I was to have encountered a relatively friendly one. I'll make sure to be more cautious in the future. But when I returned four days later, I started to hear the female Hydra screaming in pain.)
