When you go to twisted mountain and then when you are in the middle, theres a mini cave entrance you can see and when you enter it you see a ice block in the middle, when you interact it, it says It's a rock covered with ice Touching it could make you freeze.
so, do you think theres something about the ice block or does it have any connections?
Yeah there's not really much to discuss here since in Pinwheel Forest there's also a moss rock to evolve Leafeon, and considering the fact that you've been able to evolve Eevee into Glaceon & Leafeon since DPPt, a discussion about said rock won't really go far. :( PLUS! We also have a thead on Twisted Mountain so if you have any theories for that location please do post them there!
If you have any further questions about this rock though, ask in Quick Questions.
