It is a very small Tamagotchi, only a fraction the size of the previously released Connections.
Rather than having menus like a standard Tamagotchi, its buttons are now context sensitive. If the Tamagotchi needs something and you press the right button, it will play a short little animation to let you know.
The left button lets you interact with the pet. If it's hungry or needs a snack to make it happy, the button will bring up the food menu. This button is also used to bring up the menu for turning the light on and off when it goes to sleep and for flushing the screen.
There's no game in this version.
After hatching, it is already in the child stage. After 24 hours, it will turn into an adult based on the care it was given.
With good care, it lives for about two weeks.
The Chibi and Mini feature different secret characters. The adult characters have the possibility of turning into a secret character after about a week of play. The healthiest adult character, the rabbit Mametchi, can turn into Super Unchi-Kun in the Chibi, and Ginjirotchi in the Mini.
There was also a special 'Good Luck' edition of the Chibi that featured a different secret character.
Bandai is re-releasing the Chibi in April 2017 for the 20th anniversary of the Tamagotchi brand.
The Chibi and Mini are very bare-bones. They're more like interactive keychains than virtual pets. Still, they're really cute and don't take up much space at all. They're also really good if you don't have a lot of time and space but still want to care for a Tamagotchi. If you've got more time, though, you may want to look into a more interactive version.
