Chirtle [kur-till]  are initially small, spiral-shelled creatures native to the world of Cinnas. Their shells grow naturally into many familiar shapes, and they inhabit a wide variety of biomes. These creatures have a long lifespan, and can grow to such sizes that they have been known to carry a band of Cinnas across treacherous carbonated oceans, shifting sugary deserts, and fiery lakes of spice and oil.  They resemble and smell of worldly delights.

Their shells can grow in all Cinna Tail shapes, can grow to a range of sizes, and exhibit a stunning array of defenses for the natural world.
