Ice Hazard

Ice Hazards are ice blocks that can be encountered in Glacier. They are invincible and can contain a variety of objects.

= Variants =

Normal
These are the default version of Ice Hazards. They can be pushed around and will slide on the ground. Once they make contact with a wall or other solid object, they break and release their contents.

Spiky
Spiky Ice Hazards appear as part of Chuck's battle and can also be created by Jaugrs. They act like regular Ice Hazards but deal damage when Isaac touches one.

Gaper
Gaper Ice Hazards spawn a Frosty Gaper when destroyed.

Horf
Horf Ice Hazards spawn a Frosty Horf when destroyed.

Hopper
Hopper Ice Hazards spawn a Frosty Hopper when destroyed.

Drifty
Drifty Ice Hazards spawn a Drifty Ice when destroyed.

Clotty
Clotty Ice Hazards spawn a Frosty Clotty when destroyed.

I. Blob
I. Blob Ice Hazards spawn a Frosty I. Blob when destroyed. They have a very small chance to replace Clotty Ice Hazards when they spawn upon entering a room.

Brother Blizzard
Brother Blizzard Ice Hazards spawn a Brother Blizzard when destroyed.

Troll Bomb
Troll Bomb Ice Hazards explode when destroyed.

= Notes =
 * The ice blocks are invincible, and can only be destroyed by sliding into a solid surface, releasing the monster encased inside.
 * Burning Bush, however, can instantly destroy the ice block and the enemy inside of it.
 * If Ice Hazards spawn in rooms with other monsters, the player can leave the room if they defeat all other monsters except the Ice Hazards.
 * Ice Hazards will remain in rooms if the player skips them.
 * If the player breaks an Ice Hazard and leaves the room mid-fight, the Ice Hazard will not respawn.

= Trivia =
 * Clotty, Brother Blizzard, and Troll Bomb Ice Hazards were added in Sin Update. Clotty Ice Hazards replaced I.Blob Ice Hazards in most room layouts.
