The Nano-mals are handheld electronic pets measuring 2.7 inches (6.9 cm) tall, powered by included batteries. These pocket-sized companions combine digital pet care with interactive fidget play. Stardream the unicorn features a light-up heart meter that fills through fidgeting, unlocking additional interactions as engagement increases. Users can interact by clicking the ears to pet, moving the arms to dance, or pressing the mouth to simulate feeding. Additional responses are triggered by flipping, catching, or shaking the toy. A silent mode is activated by holding the nose for two seconds. When placed near other Nano-mals (sold separately), the toys interact with lights, sounds, and Nanish language chatter. Blubby includes a removable textured puffer vest for sensory play, with outfits designed for mixing and matching across characters. A keychain attachment allows for portability, making it suitable as a backpack accessory, car toy, or screen-free gift for ages 5 and up.
