Efforts to Discover a New Species - 1

My current Chokkinz is a Monster Alien (Kemono, Star 4). I want to evolve this one into the Star 5 version that isn't the Bongoz. I'm sorry, Monster Alien, but as usual, I fed it a lot of snacks until it got cavities 🪥 Then, when I had it diagnosed at the Evolution Dojo, it said, 'As it is, it seems like it will become an Ancient Dweller (=Bongoz). It's a Chokkinz that's already been discovered.' It seems that one instance of cavities isn't enough to change its evolution path after all 😢
