Some time after the Sophont uprise ended, a group of basal Bruh Cells began to eat anything they could, their more numerous teeth, sharper nose, and more developed eyes helping with this. They will eat literally anything, including their own kind, and live all throughout the ocean. They will sometimes find themselves inside larger organisms due to their habit of ramming into things larger than them to try killing it, which they will then eat them from the inside out. They are able to concentrate spite into a dark red beam that they can use to defend themselves if their jaws and nose don't cut it.
