Shape

A slut's shape refers her default body arrangement. For example, the most familiar shape by far is humanoid.
Each slut is categorized as one of eight different default shapes. Such categorization doesn't preclude her from transforming into a different shape, of course. Sometimes stunts or other effects are ore or less effective depending on a slut's shape. For example, only slutskulls are equipped in Skullball.

List of Shapes

Arranged roughly from least to most complex:

Slutskull. A disembodied head. Often floating.
Slutsack. Or "cocksock." A head attached to a body without legs or boobs. Serpents, whales, and piscine fish for example. Uncommon, and rarely found beyond submortal-tier or lower. Godsperm are this shape, technically.
Slutbust. A head attached to a body with boobs, but without legs. Often resembles a literal sculpted bust.
Humanoid. "Fleshy." Bipedal with an elf-like face (or "human-like" face). Typically two or more arms and no tail. Usually hair but no fur or scales. Includes humanoid robosluts.
Furslut. "Furry" or "Scalie." Bipedal with a critter-like face, usually including a "snout." Typically two or more arms plus a tail. Usually fur or scales, not bare skin. Includes snouted robosluts.
Polyped. Any slut with more than two legs. A pony, centaur, squid, and spider are all considered polypeds. Despite the prevalence of polypeds in a world You might remember, they're uncommon outside of critters and beasts.

A Polybed-Taur includes any polyped with a body shape more like a centaur or drider, than a horse or spider.

Amorphous. A slut who is mostly gas or fluid, and who lacks a consistent solid shape. Excludes any slut who primarily takes a solid shape.
Strange. A slut with a "strange" shape doesn't fit into any of the categories above. Examples include a solid slut without a head at all, or a truly formless slut such as an omnipresent Ωmnigoddess.

Additionally, any slut's shape can be also classified as "Winged." For example, a "Winged Humanoid" is merely a humanoid with two or more wings. Such a slut is in both the "Winged" and "Humanoid" categories.
