Cosmotchi evolves from either toddler with the "intelligence" skill.
Cosmotchi can evolve from either Mitsumarutchi or Turtletchi from perfect care. His adult evolution depends on care mistakes and personality training. As the best possible teen, he is the least sensitive to care mistakes, and is therefore more likely to evolve into Mametchi, Righttchi or Knighttchi.
