I recently got a new US v6, and my sister did as well, and my Tamgotchi says "Tamagotchi Music Star" up at the top, and hers only says "Tamgotchi" we got them at the same store, and they are both v6's. Hers was part of a booster pack that came with 3 figurines and a movie. Is that why they are different, or is it maybe because hers is the first batch and mine is the second batch, or vice versa? What does your tamagotchis say at the top?
