This is an ad — and it also represents one of the mini-games — for Sega’s follow-up to the most excellent Nintendo DS game FEEL THE MAGIC. The game is called WHERE DO BABIES COME FROM? (AKACHAN WA DOKO KARA KURU NO?), and it’s out in Japan next week (October 20). This post from Kotaku includes more ad images.
Update (16/09/04): The image is no longer available.
