Hamstar

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

Design
Hamstars are small hamster-like Dream Eaters that as of yet are only available in a "Chocolate" variety. Hamstars have a plethora of stars decorating their bodies, for which they earn their namesake, including a large star on their forehead, small stars scattered throughout its mane, as well as decorating its chest and back.

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 and, using some of Player's Chirithy's fur, creates a "pet" for them.
