Quackhead

Today Rigel made a fairly birdlike chirp, which is pretty unlike him.
"Who told you you were a bird!? You're not a birdie!"
*SquakSquackSquak!*
"No, you're not a bird! You're a puppy!"
Mumbles: *QuakQuakQuak"
"Okay, fine, I guess you are a bird. You're a duck!"
Mumbles: *QuakQuakQuak"

He's a Quackhead
