That cute Plue of yours, he could let you cuddle him all the day, he wouldn't mind. You're his owner as you're a Celestial Wizard and he would be ready to do anything for you even though he's the weakest of your spirit. He just looks like a little snowman who can just say 'Puu Pun' but is quite fond of you.

As you're sleeping with him in your arms, he wishes to become stronger, to protect you. The stars hear him and turns him. He now looks like a human. That wakes you up.
