 Rumo has white fur and a wolf-like appearance with a v-shaped marking between his eyes.Rumo, like all other Wolpertings, is capable of "seeing" scents by visualizing them as different colors and he has incredibly sharp hearing.Despite his talents in fighting and incredibly fast reflexes, Rumo is perhaps the most dense Wolperting in this novel, making his attempts to win over his Silver Thread, Rala, very difficult.
