Siblings

Cookies siblings are named Moonlight, Summer, and Sunset! Sunset is Non-Binary, Summer is male, and Moonlight is female. Summer is the oldest while moonlight is the youngest.

They are all based on a time in the day. If Cookie was too, he would be Sunrise.

Unlike Cookie, who can change color, they are all unable to change color.

Moonlight is shy, Summer is energetic and optimistic, while Sunset doesn't really like to show emotion.
