 The "TamaTown" website, formerly known as "Music City", is now used for both the "Tamagotchi Music Star" and the Tama-Go".The "TamaTown Tama-Go" includes a four-shade grayscale LCD screen, unlike the full-color screen of the "Tamagotchi +Color" or "iD".Instead of using CR2032 batteries, like previous "Tamagotchi" devices, the "Tama-Go" is powered by 2 AAA batteries.
