Roger is a Snow Man who appears in "Princess Potluck." Ice King most likely creates him for his party or brings him as a guest in order to try to make the people at the potluck jealous. Ice King gets Gunthalina to give out snacks to Roger and the other Snow Men, but she ends up shoving the snacks into their bodies. Ice King also tries to dance with Roger, but he is unresponsive.
Roger, like other Snow Men, is made out of snow. He has two arms with no fingers or hands, and three balls of snow make up his head, torso, and bottom section; he has two dots for eyes and a mouth.
