Yellow won!
Generation 19
Spuig soon had eaten all of the non-yellow algae in the area of the coast, several years passed by, and yellow was the dominant, and only color in the area. The surviving color was also a distinct shape, long and super thin, almost hair like, named Hair Weed. New creatures have now become apparent.

At the bottom, we have a Spuig descendant from generation 11, called Sand Nerves. Its colors have changed to match the sand color, and it has yellow tentacles coming off of the top of its body. It gets its name from the fact that if Spuig, or any other animal not immune to it, touches one of them, it gets a nasty sting, which is especially lethal to Spuig because its nerves are exposed. They can swim around, with the tentacles hanging downward. In the upper left, a blue cell descendant, called the Rock Ring Worm. It is immune to Sand Nerves' attacks, and will usually break off a few tentacles to eat, although it will eat its young whole. It has an effective predator, in the lower right, which it cannot eat. It is a green cell descendant, called Spike Vase, from the same line as Rockpedos, but from very early on. As you can see, from the outside it appears like a poriferan, but on the inside it has a nasty spike that will lunge into its victims. It will do this at random, you can touch it more than one hundred times, when it just goes off. It will then retract the spike, hopefully with some flesh attached. It can't eat Sand Nerves, but they will eat them.
