Thin Ice is a type of block found in the Snow and Ice biomes. It is found naturally in two configurations: either a single layer over a pool of water, or in large packed regions underground.

Similar to Ice Blocks, Thin Ice has reduced friction, and players will slide across it. Thin Ice will break if a player falls on it at a certain speed, usually achieved by falling normally onto it. Landing on Thin Ice will not cause fall damage itself, but it will not slow the player's fall on contact, and fall damage will continue to accumulate until the player lands on another block type (unlike Cobwebs, for instance, which reset fall damage). Ice Skates or any of the combined accessories that use them as an ingredient can be used to land on Thin Ice without breaking it and dropping through (also potentially taking fall damage, however).

Thin Ice is destroyed permanently when broken, dropping nothing. On the Old-gen console version Old-gen console version and Nintendo 3DSNintendo 3DS version version, Thin Ice cannot be picked up, crafted, or moved in any way.

  • When Thin Ice is broken underwater, any pool of water it is in will retain its water level.
  • Thin Ice blocks only break from the top. It is not possible to run through Thin Ice horizontally, or crash upwards through the bottom. Using a grappling hook to attach to a Thin Ice block from above will break through the block, but grappling from any other side is safe.
  • The use of a Gravitation Potion will not break the underside of the ice block. Using a gravitation potion and falling towards the top of the block will result in it breaking. This leads to the conclusion that Thin Ice blocks can only be broken from the top side.
  • Effects that slow fall speed, such as Featherfall Potions, slowing one's fall with Rocket Boots, or falling through water or Cobwebs, can prevent the player from crashing through Thin Ice.
  • (Old-gen console version) When not underwater, grappling to the bottom of a Thin Ice block can still drown the player.
