Here is a type creature that seems to be in the same family with squirrels, and flying squirrels. They can be seen climbing up trees, and gliding down from them with occasionally a glow being seen where they are if it’s dark enough, they are unable to turn that effect off. They have been know to get along very with kinds of squirrels to the point that hybrids have been seen. Think of the hybrids like a squirrel that glows in the dark, but on rare occasions some flying ones have been seen to.
(I should probably name this one, so how about gliding night squirrel)
