Snow people
Snow people are a species of sapient, humanoid snow beings that look like humans but are entirely made of snow and lack any facial features besides 2 small eyes set far apart from each other on their face. Snow people's bodies are also similar to humans. Instead of skin, snow people's skin is like compacted snow. Instead of bones, snow people have ice bones that are quite fragile. Snow people lack blood and instead have water that runs through their body and does not freeze despite their frigid internal temperature. When a snow person is hit, the water in their bodies goes to the part that was hit and freezes, making their body harder and mending any injury. This function also makes the rest of their body weaker because there is less water in the areas that weren't hit compared to the part that was hit. Snow people "eat" by pouring water on themselves, which does the same thing that both eating and drinking would do for humans.
Snow people are very susceptible to heat and the recommended temperature for their environment is 10 degrees or less. If a snow person is caught in the heat, then their snow will melt slowly and expose their ice bones. This typically cannot be healed if serious or only heals very slowly over years of time for smaller injuries.
