The Happy Pet is similar to Bandai's previous release, the Tamagotchi. Like the Tamagotchi, the Happy Pet is a pixelised creature housed in a computer worn around the wrist. Unlike Tamagotchi, which involves raising imaginary creatures, the Happy Pet involves raising a real-life animal. It operates on a touch screen. The touch screen enables the user to stroke the pet to either praise, discipline or cure the pet. The pet has intelligence and friendliness levels, depending on how well the user looks after it. However, the Happy Pet does not evolve. The three buttons can be used to feed the pet or play games with it. The buttons can also be used to see what the pet is currently thinking or feeling.
