Hatenatchi is a special baby that is born when any adult uses a Dating Card. There are three cards, and each one can be obtained from connecting the Entama to a TamaStation and playing the TamaCup game. The chances of obtaining a dating card is 1 in 5. As the TamaStation is no longer available, the only way to obtain a Dating Card is through code manipulation.
After the parent leaves, Hatenatchi will evolve one hour after being named. Depending on which card was used, Hatenatchi can evolve into either Meganetchi (Card 1), Getatchi (Card 2), or Okutchi (Card 3).
Its name comes from the Japanese words hatenama-ku which means "question mark", hence its appearance.
