A BiologyType that mimics organic biology very closely, but is not quite normal. - Body parts look shiny. - Body parts are expandable. - Very light. - Easy to move and be pushed around. - When weakened, body parts will start becoming increasingly see-through.

A biological ability to attach skin together with enough prolonged contact, creating a TemporaryConjoinment.

A BiologyType that mimics organic biology very closely, but is not quite normal. - Body parts are expandable. - Not to be confused with #PooltoyBiology, BalloonBiology or RubberBiology. - Virtually indistinguishable from NaturalBiology.

The default BiologyType that perfectly mimics normal biology. There is one exception - in certain situations, the ForceOfPlay may decide to bend normal biological rules.

RubberBiology is a BiologyType built around being made of rubber. - Outer body feels taut. - Inflatable. - Difficult to damage or pierce. - Rubber and other elastic material is consumed as input. - Stronger. - Sleeping and resting allows consumed elastic material to be used to re-strengthen the body. - The body can be gradually shaped differently by applying a pressure (such as a corset or belt) which will gradually permanently change the shape of the body.
