Pepper is Kana's cousin Dylan's hamster. She lives on a farm, so she naturally likes farm related things like animals and plants. When she visited the ham-hams in the city, she called them "city slickers" and thought they were crazy for not doing things that she did there (like run onto the road, and ride a donkey in a building to name a few!) This may make her look really wild and crazy, but she cares about the ham-hams and Oxnard especially. She's also athletic with sports like snow boarding. She is extremely good at controling annimals of all kinds. She is smart, and has a quick temper.
Oxnard and Pepper are official lovers. Oxnard first admitted his feelings in Oxnard's Big Crush. Oxnard loves her deeply, and she returns his feelings. In a later episode, Oxnard stays at Dylan's farm with her. In the last episode, episode 296, "Happy Ham-Ham Wedding! " Oxnard and Pepper return to the Ham-Hams to announce they are getting married, and invite every Ham-Ham they have met to the wedding, excluding ones only seen in the movies and OVAs.
