These geckos are (possibly) having sex and breeding. There's no other food up there (possibly). So they will (possibly) eat each other, evolve to grow stronger AGAINST THEMSELVES. THEY WILL CONTINUE EVOLVING UNTIL THEY CRASH DOWN TO EARTH AND WE WILL (possibly) HAVE GIANT CANNIBAL GECKOS
Mobile games are getting WAY too desperate for new ideas. Like have y'all seen that one of the person who's ass cheeks grow as you collect the peaches and dodge obstacles?? What the flying fuck is that...
