Ice crystals (Frost Bite)

 have appeared in all the games in the Frost Bite Series, and appeared as hazards in the Thin Ice. They appeared in the Background of levels in the Platform Frost Bite Games (Frost Bite 1 & 2), but have appeared in Thin Ice as Hazards.

In Thin Ice, the Ice Crystals appeared, attached to the ice. If the Eskimo skated into it, he would be frozen in a block of ice and pushed back. The Ice Block around the Eskimo will break seconds later. Thy can not be destroyed, only avoided. If the player is in a block of ice, and is moving backwards, and hit an enemy, they will bounce off the enemy, going the opposite way.

There is no stun, so if the player bounces off the enemy, and hits another enemy, they will still lose health. The player can sometimes control the Eskimo while it is in an ice block. Thin Ice is the only game in the Frost Bite Series where actually do something.
