The tamagorchi smart is like the uni but released before for tmgc 25th anniversary. The biggest difference is that the smart uses touch screen and has no Wi-Fi. You can download data on ur Tama smart with smart cards you can buy or get in ur special Tama smart. From what I know of 6 different Tama smarts was released. I could be wrong tho. There's two "normal" ones. 1 coral pink and 1 pastel blue. There's the one piece one as seen in the vid and there's a collab w the j-pop group niziu. There's also a special anniversary where people from Japan could join something where random people would get to buy the special 25th anniversary one. The one seen on the video the niziu one and the 25th anniversary one all comes with a smart card. Hopes that helps!
