A small figure with a blue crystal on top.
Ice Stone ( is a 氷の石 Kōri no Ishi ) ? Key Stone that appears in and its enhanced port Sonic Adventure . It is used to unlock the entrance to Sonic Adventure DX: Director's Cut Icecap in Mystic Ruins.
The Ice Stone is a figure slightly smaller than
Sonic the Hedgehog's full height. It has a grey square rock stand with an almost ellipsoid blue crystal fixed vertically on a light blue ring on top of it. Inside the blue crystal is a snowflake symbol.
The Ice Stone appears in Sonic,
Tails and Big's storyline. In Sonic and Tails' storyline, the Ice Stone can be found at the end of alleyway behind the cinema near the casino in Station Square, after the player has cleared Casinopolis. In Big's storyline, however, it can be found behind the Twinkle Park lift in the Station Square Adventure Field, after the player has cleared Twinkle Park.
The Ice Stone is to be taken by the player to the tunnel that leads to the
Mystic Ruins Angel Island Adventure Field. When passing through the tunnel to the island, the player will arrive at a cave surrounded by ice. There, the Ice Stone must be placed on a pedestal with a square blue crystal in order to open the path to Icecap.
