It's said that spotted can be mutated into tllia and vise-versa and also that reptans can be mutated into ridgeball and vice-versa. I have tried to d this many a time, losing money being wasted on useless mutation liquid. I've come to the conclusion that this will not work. I have mutated Reptans, Ridgeballs, Spotted, and Tillia, and I am almost positive that reptans cannot be mutated into ridgeballs, ridgeballs cannot be mutated into reptans, spotted cannot be mutated into tillia, and tillia cannot be mutated into spotted. Just a note, because people, such as myself, believed this would work.
