- Not to be confused with the frozen block.
The ice block is headwear worn by Blockhead Zombie that appears in Frostbite Caves in Plants vs. Zombies 2. It works similarly to the knight helm that the Knight Zombies use and the skull that the Jurassic Fossilheads use, but it cannot be stolen by Magnet-shroom nor does it have any weaknesses.
The ice block absorbs 1600 damage per shot. Its appearance changes upon absorbing 534 and 1067 damage per shot, before completely cracking at 1600 damage per shot.

- Despite being made of ice, it does not take any extra damage by fire-based plants and cannot be melted by a Hot Potato.
