Rainicorns

Rainicorns are a species of unicorn/rainbow hybrids that live in peace in the Land of Ooo.

Background
Little is known about the background of the Rainicorns, other than there was a Rainicorn-Dog War. One dog saved Bob during the war, so he and his family Ethel and Lady are friendly to dogs. Lady, Bob, and Ethel are the only known Rainicorns in Ooo. They all speak Korean, though not all rainicorns do.

Appearance
Rainicorns are unicorn creatures with almost a full rainbow of colors down their body. They range in length; Ethel is about twice as long as Lady, who is in turn three times as long as Bob. Bob is roughly the length of a normal horse, though shorter in height. The only shown rainicorns are rainbow-unicorn hybrids.

Abilities
All rainicorns possess the ability to fly by intercepting beams of reflected sunlight and "dancing around on them." They also have the ability to change the color of any object by shooting it with a chromatic beam fired from their horns, and the power to stretch their bodies out to various lengths, much like Jake.

Notable Rainicorns

Trivia

 * Jake claimed that for thousands of years the rainicorns battled the dogs over territory in the Crystal Dimension. The outcome of the war is never outright stated, but it can be inferred that the Rainicorns have some stake in the dimension today as Lady Rainicorn's parents come from there in Her Parents.
 * Rainicorns may or may not eat humans as in the episode "Her Parents" Ethel and Bob Rainicorn try to eat Finn. They then enjoy a picnic of "soy human" which is supposed to taste just like the real thing. Finn also says it tastes good.
 * There is an alternate version of the Rainicorn-Dog Wars, the Monochromicorn-Cat Wars.
 * Rainicorn is 무지개콘 (p ronounced 'mu-ji-gae-kon') in Korean.
 * Even though rainicorns are rainbow hybrids, they do no have the color orange on their bodies.
