Princess Princess Princess makes her first appearance in "What is Life?" in Ice King's Imagination Zone. She later reappears in the episode "Loyalty to the King" when she bumps into Finn and Jake, saying she wanted to meet the Nice King. She then appears three seasons later in "Princess Potluck" attending the potluck of Princess Bubblegum. According to the events in "Princess Day," she is a registered princess.
Princess Princess Princess is a princess who has five heads, all of which have a unique crown or tiara. The center head has blonde hair that has a crown with many spikes and is yellow, the head on the right shoulder has auburn hair and has a tiara that looks like a spade with a bright blue jewel in the middle of it. The small head underneath the previous head has brunette hair, and her crown has two spikes on it. The head on the left shoulder has strange green hair and is drastically different from the other heads; it has a monstrous appearance with large red eyes, sharp teeth, and always has its mouth open and salivating. The "monster" head has a tiara that looks exactly like Turtle Princess, Princess Bubblegum, Embryo Princess and Slime Princess' tiaras, but with a ruby-colored gem. The final head is underneath the "monster" head. It is small like the brunette head and has navy blue hair, she has a crown similar to the blonde head's but with a darker yellow color and fewer visible spikes. Princess Princess Princess' skin is attached to her dress and all of her heads, except the "monster" head. Each head also has a slightly different voice except for the "monster" head, which has not been heard yet. She sometimes speaks alternating between heads per phrase, implying she may be one mutated princess.
