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 3DS3DS version 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 ( Ice Chests) can be found naturally.

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.

On the 3DS3DS version version, normal-sized worlds only have a 1/3 chance of containing a snow biome, and their respective underground. Furthermore, Armored Vikings, Snow Flinx, Icy Mermen, Ice Tortoises and Ice Mimics will spawn much more rarely than on the Desktop version Desktop version, Console version Console version, Old-gen console version Old-gen console version, and Mobile version Mobile version.
