OK! Needing some help with the new pets.

OLEG Or Oli as everyone calls him, is a Russian immigrant who moved to the states a year or two back. As a result his English is still a tad broken from not taking proper classes. He works at a fish monger for a living and is totally poor. But he's a student at an art college, majoring in dance. He's classically trained in ballroom, his mother was a ballerina.

JAE-SUN His family is Korean but he was born in Chicago. He moved to New York to pursue dance and works at a coffee shop and is very disgruntled about it. Far more happy and spunky than Oli. He's not classical trained, instead he's a hip-hopper with contemporary experience. He spends his free time attempting to teach Oli how to loosen up while Oli teaches him ballroom.

I mostly need suggestions on what kind of pets they should be. I'm at a loss.
