His hair care routine... oh goodness. He takes showers that're at least an hour or so long. If he's feeling lazy, his servants will wash his hair for him. An entire bottle of shampoo, conditioner, detangler... It's a very, very complicated process. 

His backstory..... I'm still deciding whether or not to reveal it! Part of me wants to, and yet another part of me feels it should remain shrouded in mystery. Ho ho ho.

To answer your first question about the stuffed animals -- he collects stuffed penguins, primarily! He relates to penguins on a spiritual level because they are flightless birds like himself. 8D But other than that, he mainly just collects anything that's super soft and close to the approximate size of a person, as his stuffed animal obsession is actually just compensation for the fact that he can't touch or hold anything that is living.

His wings can't be restored, no! But if he were to take better care of himself, they would improve a little bit. Not enough to have him start flying again, though, nor change color.
