It's very unique. It has no icons or menus. When it needs something, you press the A button to fulfill that need, like feeding meals or snack, cleaning poop, healing its illnesses or turning out the light. It starts out as Marutchi for ne day then evolves to an adult. I got Mametchi the first time, then the secret character Unchi-Kun. This time around I got kuchipatchi and am trying to get unchi-kun again.
