The Royal Corgis are the noble canines of London in 101 Dalmatian Street. The group first appears in "A Right Royal Rumble," in which Prince Corgi, Princess Corgi, and Prince Waffles are featured in a parade in Camden Town. Clarissa is particularly dazzled by them, as is Dolly when Prince Corgi reveals to her that he also has a passion for skateboarding.
The Royals later appear in "Yappily Ever After," in which the group attend the viewing of a tennis match at the park. This episode introduces an unnamed brother to Prince Corgi who, unlike his siblings, hates the attention that comes with being royal. He later forms a friendship with Dolly over their shared love of skateboarding.
In "Yappily Ever After," it is implied that the Corgis live in either Windsor Castle or Buckingham Palace. Additionally, Prince Corgi's brother is shown to have the same speech affectation as Clarissa in that he refers to himself as "one."
