Pupmoon

Dog Moon is a Dream Eater that appears in Kingdom Hearts Union χ.

Design
Dog Moons are small black-nosed, dog-like Dream Eaters that come in a base variety of either orange or blue. Due to their small size and initial coloring, they closely resemble the breed. Dog Moons have a noticeable yellow crescent moon on the center of their heads, earning them their namesake. There are also three stars of various shapes placed about their body: a small star towards the center of their body, a medium-sized star directly above the smaller star, and a larger star on their left ear. Despite their main body color, the fur on their tail, paws, chest, and underbelly are white.

Kingdom Hearts Union χ
Following the events of the Keyblade War, the new Union leaders, Ephemer, Skuld, Ventus, Brain, and Lauriam, decide to celebrate by providing new Spirits for the Dandelions. Ephemer goes with Skuld and Ventus to collect the necessary ingredients, while Brain and Lauriam stay behind in order to prepare. Soon after, a Chirithy approaches Player and, using some of Player's Chirithy's fur, creates a "pet" for them.
