Sun is a jester-like animatronic with a stylized light-beige sun-shaped head, white eyes, and a widely-grinning expression. His entire body is predominantly colored beige and amber, being dual-colored down the middle from his face to his torso. The right side of his face is beige while the left side is amber (including the teeth). The right side of his face and torso both slightly overlap the left side: for his face, it curves over at the top and bottom and overlaps onto the amber side with a 2D/flat, pointy nose and outline on the mouth, forming the illusion of a smiling, waning-crescent moon, which is directly referencing Sun's counterpart, Moon. His body slightly covers part of the amber side at the top where two maroon buttons are at. His head has spikes on its perimeter that resemble sun rays. He has a lanky body with long limbs and large, opposable five-fingered hands, colored in a gradient from beige to gray with gray fingertips. Sun is fit with a beige-amber painted torso that corresponds to his facial colors, yellow pants with maroon stripes, and a faint maroon gradient that can be seen just above the fabric sash of his waist frills. Both his neck and waist frills are maroon with a yellow stripe. Sun also wears orange elf-like shoes with a star symbol on the outer part of the shoes, and a moon symbol on the inner part. He has maroon ribbons with bells wrapped around his wrists. Sun is upbeat and energetic, shown in his constant excitement. Though he can sometimes be angered, it takes much to get there. His trust is easier to gain than Moon's, but both of them are very, very loyal. It does not take him much to worry, however, as he can sometimes give off a motherly attitude. His personality matches his name, sunny, bright, and joyful. Wears bells for blind children to hear. Full name is Sundrop but he prefers to be call Sun or Sunny. Will call other people nicknames too, mostly, Sunny, Sunspot, Starlight and/or Friend or New Friend.

Moon, similar to his daytime counterpart, is a jester-themed animatronic, but with a head bearing the likeness of a grinning crescent moon rather than a bright sun. After transforming into Moon, the sun rays surrounding Sun's face are retracted into his head; the left half of his face turns black with the detailing on his teeth and eyes still visible; and the right side of his face, shaped like the crescent moon, turns white, giving the smiling moon illusion (stated in Sun's description) more contrast and prominence. His torso is painted silver and black instead of beige and amber respectively, but the two buttons located on his chest remain in place and are colored blue instead. His arms are silver and gradient to blue towards his forearms, and his hands and fingertips are also colored blue. On his head, he wears a sleeping cap that is blue in color and patterned with bright yellow stars, and the end of the cap is decorated with a golden bell. He has blue and gold frills around his neck and wears puffy blue pants accented by yellow stars. Identical to Sun, Moon's waist frills remain maroon and gold, his shoes are still orange with moon and star symbols on them, and he maintains the same maroon ribbons and gold bells on his wrists. There is also a small latch on his back which connects to a hook, allowing him extra midair mobility. Moon is calmer, more composed, and can be quiet. Though he is lightly mischievous and playful with those he knows and trusts, though his trust is harder to gain than Sun's. Wears bells for blind children to hear. He prefers to be called by his full name—Moon or Moondrop, but if someone can gain his trust and get close to him, he will allow Moony as a nickname. If he gets close to others, he will nickname them Stardust, Starlight, or when he's feeling playful, even Princess. Otherwise, he usually uses a person's name.
