The 老鼠 is a 小动物 and cannot harm players. However, unlike most critters, they cannot be harmed by monsters. Mice have only 5 health. They spawn in the 地下 and 洞穴 layers. Their small size and speed can make them difficult to spot even in well-lit conditions, although they occasionally squeak. Unlike most other critters, NPCs will prevent mice from spawning.
A 金老鼠 may also spawn instead. Mice can be captured with a 虫网.
- The Mouse more closely resembles a real-life rat rather than a mouse as it has a "naked" tail. In real life, rats have "naked" tails while mice have furry tails.
