Bonnie Prince Derek Grunkwitz of Dreamland is the son of King Zøg and Queen Oona, and younger half-brother of Princess Bean. He is the youngest child of Zøg and his only son, so he is the Crown Prince and Heir Apparent to the Throne of Dreamland.
Like his mother, Derek has blue skin and black hair. Derek has hair covering half his face, but when he removed it from its obstructing position, it is shown he has a unibrow. His hands alternate between having the 3 fingers of his Dankmirian heritage and the 5 fingers of his human heritage, though this could be an animation error (he is usually seen with 5 fingers).
Derek is shy, quiet, naive and introverted. He is shown to love to play with his is toys, and loves to watch the news. Derek is afraid of skillets due to being almost cooked alive.
Zog is Derek's father. Like with Bean, Darek's relationship with his father appears to be a weak one since Derek was scared of having to be alone with his father while Derek's childish behavior frustrates Zog although Derek was happy when Zog visited him his bedroom while Zog had the guards take Derek away so that Oona couldn't find him.
Oona is Derek's mother. They don't interact much in the series although Derek seems to like her better than Zog.
Bean is Derek's older half-sister. He served as the "flower boy" for her first wedding and seems to respect/listen to her to a degree.
