Sky is a male cyan/sky blue Sprunki with circular, bear-shaped ears and a cowlick. Unlike actual bears, he doesn't seem to have a tail. He is typically depicted with a calm demeanor, exhibiting a bright, heartwarming style.

In these loops, Sky moves his head while alternating his facial expressions, producing a music box sound synchronizing with Gray. His mouth changes according to the note's pitch; for example, he smiles when reaching his highest note.

Sky would let out a music box sound from his mouth. He crosses his arms over his chest as he hums and awe's his tune majestically with the rest while looking at some of the sprunkis, or his friends such as Gray, Simon, Wenda, etc.
