this is a 'sfw' ref for underwear critters for people in 'sfw mode'

• capable of photosynthesis. they're made of cotton, after all
• no nose, ears, or mouth. some have eyes and some don't. either way, they can see, breathe, and speak
• can absorb water
• colours and patterns can be different, and are not always inherited
• sock-like feet. toes are fused together
• mitt-like hands. all fingers except the thumbs are fused together
• they can have hair made of the same cotton as the rest of their body, though not always
• they have lizard-like tails that i keep forgetting to draw
• permanently fused irremovable underwear. it is a part of their body and is impossible to remove.
• underwear critters are 100% cotton, their bodies lacking the organs that animals have.
• underwear critters can tf other animals.

the species is made by me, but it is an open species that you are free to use
