Moon first appeared with Bad [TBA]. On Day 297, Tubbo first met Moon after accidentally punching Sunny, which startled him, and periodically showed up that day, but Tubbo calmed them down with a calming melody. After hearing about how Leonarda griefed her statue with a pack of dogs, Moon came back out and he went over to Leo’s statue with a mine, but just put a sign down saying she was possessed and Moon went away again.
Moon hates money, and because of this Sunny dislikes Moon.
