CooperCentaur

There's an 8-legged version, but it has issues with the number of legs.

There's also an issue with the character turning into a pure horse.

Additional tags for 8 legs: multiple legs, 8 legs, 8_legs_centaur, eight-legged_centaur, eight_legs_centaur.

If you want a horse sheath, enter the tag: sheathed. (A sword might appear, I don't know how to fix it)

You can also write a tag for the penis: horse_penis.

If you want a shell then: sheathed
