Marumofubiyori is a trio of Sanrio characters. The main character is Mop, a polar bear cub who is always draped in his favorite blanket and loves to laze around at home. He is a home person who lives with a roommate that works at an aquarium, which gave him this nickname because he always drags his blanket around as if mopping the floor. The other two are a blue fish Gyoniku and a red crab Kanikama. Fanart Marumofubiyori and Gyoniku Sanrio cursor pack.
