Impossible Creature Generator

An impossible creature generator that checks its own anatomy. Combine real animals into a hybrid, or specify a creature — habitat, mass, diet, locomotion, body covering, thermal strategy — and twenty-one deterministic rules test whether it could actually live: wing loading against mass, exoskeleton mass fraction, fermentation gut volume, surface-to-volume against habitat temperature. Then it renders the result as a naturalist's plate. The composer, the coherence report and the content guard all run in your browser before you spend anything.

Every public app is built from a security-scanned skill and must pass a clean scan — skill and frontend — before it can be listed. Have a skill of your own? Turn it into an app — or read the step-by-step walkthrough.
