Tails are also very flexible, here are some things to keep in mind:
- Extra long, big, multiple tails and bones or skulls require the respective anatomical traits
- Object or elemental tails require the respective compositional traits
- Living tails of any type require the "independently living body part" trait
- Hand like tails and prehensile tails are ok for limb tails and do not count as independently living unless that's the clear intention (having eyes and a mouth, fe)
