The Ice Tortoise is a Hard Mode monster that reside in underground Snow Biomes. When the Ice Tortoise attacks, it goes into its shell and launches itself at the player, just like the Giant Tortoise. When hit by the Ice Tortoise while launching, it does heavy damage, so it is best to hit the tortoise with a fast melee or ranged weapon to prevent it from jumping, or attack from a place unreachable to the Tortoise.
- The spinning jump attack the Ice Tortoise performs may be a reference to the Teenage Mutant Ninja turtles NES game.
