Engagement Ring Princess

Engagement Ring Princess is a recurring character in Adventure Time, first appearing in "Ricardio the Heart Guy" and later in "What is Life?"

She is often seen at various parties in the Candy Kingdom. Her role evolves over time, with her becoming a prisoner of the Ice King in "Loyalty to the King" and later one of the suitors for the Nice King. While in captivity, she calls out repeatedly, "Save me, Finn and Jake," though Finn believes her distress is more a result of trauma than true danger. In "The Lich," Finn and Jake attempt to remove a golden ring embedded in her head while she sleeps, as the ring's gem holds the power to activate the Enchiridion. Despite her unusual appearance, she is officially recognized as a princess in "Princess Day."

Her defining feature is a golden ring with a blue gem on top, which serves as her crown. Engagement Ring Princess has light blue skin and short pink hair. She dresses in a white strapless gown that reaches the floor, accented by a large purple bow around her waist. Her design was inspired by the archetype of a frantic, desperate bridesmaid, a nod to romantic comedies, as explained by series creator Natasha Allegri. She also enjoys opera music, as seen in "Loyalty to the King." In "The Lich," her bed is humorously depicted as a giant ring box, further reflecting her obsession with the ring.

Her voice, high-pitched and somewhat whimsical, is similar to that of Wildberry Princess, with both characters being voiced by Maria Bamford. While officially listed as a princess in The Adventure Time Encyclopaedia, she is referred to as a "Candy Kingdom Princess," suggesting she is part of the larger Candy Kingdom rather than ruling her own domain.
