Question: how to evolve eevee into a glaceon pokemon sun?
Answer: Same deal as Leafeon, just with a different rock. This time, go to the Pokemon League, go inside the mountain, and find a frozen rock, which says "It's a rock that is covered in ice. Touching it seems likely to freeze you solid!" Now wander around, get into fights, and level up Eevee to turn it into Glaceon.
