Ice biome
The Ice biome, also known as the Underground Tundra or Underground Snow biome, is a biome that is the underground version of the Snow biome, starting at the Cavern layer and stopping at the lava layer. On the Nintendo version, the Ice biome starts at the Underground layer. It is composed mainly of Snow Blocks and Ice Blocks. Thin Ice can be found generated over water and breaks when a character falls over 4 tiles onto it (unless using the Ice Skates or another accessory crafted from them). The Ice biome is the only place where Frozen Chests ((Old-gen console and 3DS versions) Ice Chests) can be found naturally.
The player is considered to be in an Ice biome if they are below the border of the Underground and Cavern layers, and there are at least (Desktop, Console and Mobile versions)1500 / (Old-gen console and 3DS versions)300 Snow or Ice Blocks nearby.
In Hardmode, the Corruption, Crimson, and Hallow can spread through it, generating Purple, Red, and Pink Ice Blocks respectively. They are unable to spread through Snow Blocks. In these infected areas, all of the Ice biome's enemies can spawn, in addition to the enemies from the respective underground evil biome or Hallow. Furthermore, the Pigron spawns exclusively in infected Ice biome areas.
On the Nintendo version, normal-sized worlds only have a 1/3 (33.33%) chance of containing a Snow biome, and thereby an Ice biome. Furthermore, Armored Vikings, Snow Flinx, Icy Mermen, Ice Tortoises, and Ice Mimics will spawn much more rarely than on the
