Leelu

Leeloo is a narwhal which Philip J. Fry is very fond of as he works with her from 2003 to 2010. He tries to catch her during 2010 to 2012, but when he does, he ends up setting her free. Leeloo is most obviously an animal representation of Leela, which is also apparent from the name similarities.

Biography
In 2003, Leeloo winds up in Atlanta city, but is soon taken to New York. There she won't eat, but as soon as Fry arrives, she gets her to eat. And they become the best of friends. But sadly, after 7 years of friendship, she must be released into the wild again.

But Fry will not give up, he sets out to catch her. It takes him two years, but finally he manages. But holding her captured for several days makes him realise that she is in love with another narwhal, and it cannot make him happy to watch her wanting to get out. So he decides to release her.

Trivia

 * The similarities/connection between Leela and Leeloo are quite many and obvious.
 * Obviously their names.
 * It is noted by Fry that he "likes things that have one thing instead of two", but in reality, narwhals only have one horn.
 * As many times as possible, when there is a fade from Leeloo to Leela, the horn is placed where Leela's eye is in the following scene.
 * Notably, Fry says a lot of the same things to Leeloo as he does to Leela.
 * Leeloo was coloured purple as a reference to Leela's hair, while the male narwhal she is in love with is coloured orange like Fry's hair.
 * After the writers did the scene, they realised that it was rare for a female narwhal to have a horn (which is common for the male narwhals), they thus changed the line to introduce her as a "rare" female narwhal.
