He is still awake. I guess it's Halloween. So there is no reason why he should be sleeping through this. Go try. He is said to give 1 level up for your pet.

The rules is that once you have gotten the avatar, if you play and lose, you will lose that avatar. So I am not going to try.

But for those who haven't got the avatar, give it a try.
If you win, your pet gain a level.
If you lose, your pet lose a level.

To get the avatar, you have to draw with the count and win him.

He is at the Roo Island or Here.
