These are ideas I was pitching to various publishers/producers in 2017, which never got picked up by anyone. These are taken directly from my pitches, when I was asked to come up with examples, or a set number of ideas, for an article or book.

Bybbin—A long, flat, ribbon-shaped creature like a very flat snake. Uses loops of itself as its arms and hands. Has a single featureless eye at the front and back of it’s form, and “eats” by using a few loops to engulf and crush something that is then absorbed through its skin. Secretes acid, can spray it, and can hear (its whole body is able to pick up vibrations), but needs a mechanical aid to speak.
Envisioned as a sentient and sapient species. Could be a playable species. Could have multiple stat blocks.

Fundamental Dragons — Following the presentation format of chromatic dragons in Alien Archive, but the dragons are spacefaring creatures linked to fundamental forces. Thus there would be electromagnetic dragons, gravity dragons, strong atomic dragons, and weak atomic dragons. Could also add a dark energy/quintessence dragon, or quantum dragon, to get to the traditional 5 dragon within one category. Opportunity for dragons to interact with solarion and vanguard abilities and themes.
Can do any range of CRs.

Ruhnk—A creature shaped like an inner tube, with dozens of tiny tentacles spouting from the “sidewall” of its ring, eyes along its outer wheel (hard crystal eyes that it can roll over), and mouths lining the inner ring. A sentient scavenger that eats whatever it finds off the floor nonstop, the way other races breathe, and has no sense of shame or humiliation—to exist is its own justification. Moves by rolling.
Can work at any CR up to 9 or so. Could be a playable species, or be more monstrous. Could have multiple stat blocks.
