- Not to be confused with Frozen Rock, an item that evolves Eevee into Glaceon in the Pokémon Mystery Dungeon games.
The Ice Rock is an ice-covered rock that enables Eevee to evolve into Glaceon that was introduced in Generation IV.
It allows Eevee to evolve into a Glaceon when leveled up in the same level/area containing it. Doing so overrides the mechanic of evolving into Espeon, Umbreon and Sylveon.
In Pokémon: Sword and Shield, the source of evolving Eevee into Glaceon has been changed into being exposed to an Ice Stone.
