The Kazilleon has slithered into My Singing Monsters!
"Kazilleons aren't the greatest-smelling monsters. For one, the toxic gas they spew when they're singing has been known to singe fur and upset appetites. To boot, the noxious fumes emanating from their color-shifting skin is sometimes harvested to help strip paint off of old buildings. The thing is, they're so friendly, everyone wants them around anyhow."
