Reference of Sleepyhead. c:

The color thing, let me explain.

The gems on his shoulders, those colors are always the same, however, inside the gem, they swirl and glitter, almost like a colored snowglobe. When one looks at the gem, his body changes to the color they want him to be. When they pick that color, he is set like that in their eyes, and ONLY their eyes, forever. He will retain his markings, but he will be the color of their choosing.

The mobile above his head is said to cause whoever is looking at him while it starts to spin and play it's music, it makes them drowsy to eventually where they fall into a deep sleep. They will wake up however, it just relaxes their body and causes them to rest until they are completely rested.

Oh. and his tail is Prehensile. He uses it to grab tree branches and hang upside down on it to sleep. Like a opossum. Whenever you see him rear and then lay next to a tree, he is hanging upside down. Or if he's laying in a tree, he's upside down.

I like Sleepyhead. 8D
