IDog was a really great 2000's/2K "robot dog" franchise from Japan and the U.S. , the reboot could combine the Japan IDog and U.S. IDog's features into one/globally.
Both as physical IDog robots (various colors, with removable stickers if you want) and as digital, customizable IDog robots (whose colors can be changed freely at anytime - and you can also purchase clothing, mittens, hats for your IDog too).
These toys were sold from 2005-2009 (I was three-seven years old).
Even McDonalds sold mini IDogs as happy meal toys. I had one (a mini white IDog). I loved it.
IDogs also 'dance' to music, especially if you connect it to an MP3 player/IOS device's MP3 route.
Nintendo Switch 2 really needs an awesome digital "IDog" game. It'd be similar to Tamagotchi games, with various minigames and WiFi features/invite other players over for an IDog playdate.
