The original digital pet with a stained glass bowl in a winter motif. The Stained Glass series is rare and only available in limited quantities and comes with a certificate to confirm its authenticity. With the original Generation 2 programming, you feed it, clean up after it, look after it and even discipline it if it bothers you, even though it doesn't need you. You can also play the numbers game. How you look after your Tamagotchi and how you perform in the game determines which adult Tamagotchi you get.
