The Dancing devil is a recurring monster in the Dragon Quest series, first introduced in Dragon Quest VIII. They are demons known for their dancing skills.
Dancing devils are humanoid demons with magenta skin that hop back and forth on each foot in battle and use their wicked dancing skills to trip up adventurers starting on their journey. They have small sunken yellow eyes with black sclera, a tiny pair of horns on their head, and a huge pair of pointed ears. The devils wear brown pointy shoes, a short purple capelet, and a pair of blue trousers which they are rumored to drop in battle. When attacking, they leap into the air and shock enemies with dark energy from their hands.
When the sewers under Domus Isle can be accessed, there is a man waiting down there with a dancing devil looking for an owner (no scouting is required).
These prancing princelings are monsterkind nobility and take up the top spot at every dance competition they enter. Possibly because no judge wants to upset their demonic dads
