They are impulsive and have much energy to spare. They are strong willed and have the stamina to survive the toughest of times. They never back out of a challenge. While they face the challenge in the eye, they often mistake its true nature and realize only when things are in motion. Moondrop is more chaotic than other animatronics, though,  and seems to make more of an effort to intimidate children with his words as well as his actions. Sun and Moon go by He/Them as they are brothers.
