I have 2 Tamagotchis -- one girl, one boy. They had baby girls yesterday. Twice today I noticed something weird on the screen. The bottom half had the grown up Tamagotchi and baby Tamagotchi as usual. But the upper half of the screen had what looked like a snowman in the upper left hand corner. The upper half of the screen was black with white dots, so it looked like a night sky with twinkling stars. The snowman was smiling and dancing a little. What's up with that?
