Lunar Freeze and his Egg

On the Left, is Lunar Freeze before he hatched. On the right, Lunar after hatching from the egg. His egg was an Umbreon egg as you can tell and obviously he hatched as a fully evolved Pokemon. This is why he's a fully evolved Baby Umbreon. He hatched from an Umbreon egg, thus ending up half normal and shiny.

Why his egg was produced like this: Lunarous' Genetics were less than unstable, so when Tinsle laid his Egg, it was produced as an Umbreon egg at night. Then two weeks later, one Friday night, the egg hatched into an infant Umbreon, Lunarous "Lunar" Moonlight Freeze, was given his name that night.
