Estimated arrival: Mid to late July 2026
*This pre-order item is not available in retail stores until stock arrives.
A collection of treetop friends with strong personalities, but always a little slow, a little sleepy, and perfectly okay just as they are.
Like little wearable virtual pets, these characters bring a sense of companionship and comfort to everyday outfits, like having a familiar friend around throughout the day.
Where Curiosity Meets Creativity
Inspired by the concepts of “intellectual development” and “aesthetic appreciation”, this animal-themed collection brings everyday creatures to life, turning playful animals into engaging companions for little ones. Thoughtfully designed with interactive 3D details, each piece encourages touch and play to stimulate sensory growth and strengthen fine motor skills, while the playful designs help little ones connect, interact, and make new friends.
