I went to walmart yesterday to buy a tamagotchi and i found a all white tamagotchi with no yellow borders but there are yellow buttons. so is this color new or old?, because i was not able to find it anywhere on the web. i also found a metalic purple tamagotchi connection and i bought it because it was so pretty but i was not able to find that color on the web as well. so are those two colors the new ones are the old ones??
