Tanren Mines

Tanren Mines, shortened to TM or "Mines" by players, is a mainly Rock- and Ground-type dungeon in Tanren, found north of the road fork south of Tanren City. The dungeon has 28 Floors, and supplies HM Rock Climb. You can continue onto Tanren Mines Depths optionally, if you bring along a Pokémon that can learn Rock Climb. The weather in Tanren Mines is always clear. Starting on Floor 23, Hippowdon can spawn so sandstorms may appear due to its Ability Sand Stream.

Boss
A Nidoking and Nidoqueen are found at the end of after the last floor of. The two Pokémon try to break down a wall, but then, they quickly mistake the player as an enemy and attack. After defeat, Nidoking apologizes to Nidoqueen for failing, but then they realize that the player is friendly after Nidoqueen points out how blind they were, and Nidoking and Nidoqueen ask the player to rescue some miners while Nidoking explains about the monster that Nidoking and Nidoqueen mistook the player for. Nidoqueen praises the player before a pathway is revealed. Nidoqueen wishes the player good luck before walking off with Nidoking.

Before Fighting: After Defeating:
 * Nidoqueen: How much longer is this going to take, Nidoking?
 * Nidoking: I'm almost done. A little more and this wall should give.
 * Nidoqueen: W-What if that THING comes back for us?
 * Nidoking: We managed to escape it, didn't we? Don't worry, Nidoqueen, we don't be fighting that monster again anytime soon. Besides, it should be too slow to catch up wi--
 * Nidoqueen: AAAH!! N-Nidoking quick! It's here!!
 * Nidoking: Crud, it followed us!? Stay close, Nidoqueen, we make our final stand here!
 * Nidoking: We just aren't strong enough. I'm sorry, Nidoqueen, I tried...
 * Nidoqueen: No, wait... Look! Oh, how could we be so foolish, it's just an explorer!
 * Nidoqueen: Oh dear, please forgive us! We thought you were the monster. We didn't mean to attack you like that...
 * Nidoking: I should explain. I'm sure you've heard of the mining team that got lost down here. My partner and I came here to investigate.
 * Nidoking: We were doing fine until... Well, we found some sort of ancient ruin, deep in the mine.
 * Nidoqueen: We think the miners are still there somewhere. Their supplies were scattered all over the cavern. We think they might have awakened some sort of ancient Pokemon...
 * Nidoking: The same monster that caught us by surprise and overpowered us. We couldn't even dent the thing, so we made a run for it. We decided to rest in here for a bit before we head back out.
 * Nidoking: If you still want to go down there, I won't stop you. I'll finish clearing the path, but be careful down there. The deeper you go, the more dangerous it gets...
 * Nidoqueen: You're very strong, and I know those miners are still down there. Please... save them. You're their only hope now.
 * Nidoking: Alright, the path is clear. Let's get out of here, Nidoqueen.
 * Nidoqueen: Farewell, and good luck.
