Foolduke is a royal court jester of the Butterfly Kingdom of Mewni and, as of "Booth Buddies", Ruberiot's wife. She first appears in "Marco and the King".


Foolduke is a young female Mewman with brown skin, blonde hair, and brown eyes. She wears a light blue long sleeve shirt with three light purple diamonds on the front, blue pants and pointy shoes, and a blue jester's hat with golden bells on the ends.

In "Booth Buddies", she wears a pink and white wedding dress with white gloves, and a choker with a heart on it. She still wears her jester's hat, but with a wreath of purple and pink flowers on it.


Foolduke first appears in "Marco and the King" after several straight days of partying with King Butterfly at Butterfly Castle. After waking from being unconscious, she asks the king where her pet monkey is, unaware that he tossed it out the window a few moments earlier.

In "King Ludo", after Ludo has taken over the castle, Foolduke, Ruberiot, and Mime Girl go into hiding and use his royal amenities whenever he's not around. When Ludo returns to the royal bedchambers, Foolduke and her fellow performance artists sing a song to distract him while Marco Diaz tries to steal Ludo's dungeon key. Mid-performance, Ruberiot and Foolduke begin to argue, and Foolduke manages to steal the key in the process. When Ludo banishes King Butterfly from the kingdom, Foolduke and her friends form a resistance movement with Marco to overthrow Ludo's reign.

In "Toffee", the Resistance's tactics mostly involve ruining Ludo's credibility. After they are captured by Ludo's monsters, Marco is rescued by Queen Butterfly and Buff Frog, and he leaves his fellow freedom fighters behind, much to their sadness.

In "Scent of a Hoodie", Foolduke and her fellow performance artists bid Marco farewell as he prepares to depart for Earth, with Foolduke asking him if he can stay a little longer.

In "Booth Buddies", she gets married to Ruberiot.

In "Conquer", she is briefly seen as one of Meteora Butterfly's victims.

In "Escape from the Pie Folk", Foolduke is revealed to be one of the Pie Folk of Pie Island. She visits her home and family with Ruberiot, and she assists with the liberation of Queen Butterfly from the Pie King.

In "Cornonation", Foolduke takes part in an impromptu talent show in the middle of Eclipsa Butterfly's queen coronation ceremony.

  • Foolduke is voiced by Natalie Palamides, who is best known for providing the voice of Buttercup in the 2016 reboot of The Powerpuff Girls.
  • Foolduke greatly dislikes the rest of the Pie Folk, due to their thieving, con artist ways (which she does not share), which is what led her to leave the island.
