I know how to tp to the nearest fox regardless of what type it is. It would be performed via the following command:
/tp @s @e[type=fox,sort=nearest,limit=1]
However, I was wondering how would you specify that the mob you are typing to must be an arctic fox? I tried implementing what this post was talking about with adding nbt data to it. So I tried the following command:
/tp @s @e[type=fox,nbt={tag:{EntityTag:{Type:snow}}},sort=nearest,limit=1]
But it still didn't seem to work and error out. Could someone give me a correct command to do this?
