Peter became a Volbeat this time.
The hair is always weird to get used to, but this time it has a mind of its own. No matter what he does it stays styled as it was when he woke up the day Cirque began. Despite this he has the compulsion to keep checking it.
Then there are the WINGS! He has never had wings before so those should be fun.
He also has some odd spots on his lower back that glow when he's excited ( which is all the time). He designed his new outfit around showing them off. The window in his jacket glows like one big bulb.
