Glacie was a limited edition hoverboard in Subway Surfers Winter Holiday. Like any other hoverboard, it will protect you from crashing for 30 seconds. When crashed, the board will explode and recharge for a few seconds before it can be used again. It has no special ability. The hoverboard resembles a ice crystal.
Glacier is a resemblance of ice in Antarctica, meanwhile Malik (the Winter Holiday Special) is dressed as a polar bear which is Antarctica.
