Tomagatis, or "tomagotchis," are virtual pets that originated from a handheld electronic toy created by Bandai in the 1990s. Users care for these digital creatures by feeding, playing with, and nurturing them to ensure their well-being. If neglected, tomagotchis can become ill or even "die," emphasizing the responsibility of pet ownership. These toys have evolved over time, leading to various iterations and adaptations in games and mobile apps.
