The Moonlight Costume is a retired costume that was available via the Account Upgrades Marapets 10th Birthday Set from July 2014. Putting this costume on your pet will make it shine like the moon. Moonlight pets are upset with an indigo and aqua coloration, blue dots to indicate stars, clouds surrounding them, and a crescent moon marking on their head. It is a tribute to Marapets' brand new site layout and is the opposite of the Daylight Costume.
