After the death of Marshall's father, Marvin Eriksen Sr., Marshall stayed in Minnesota to look after his Mom. After being alone in her apartment for so long without Marshall, she went a little crazy. She started off by putting Marshall's jersey on her body pillow, but soon spiraled out of control from there, when she began to have romantic dinners with Marshpillow and the two had conversations (where Marshpillow answered back). When Marshall finally returns to New York, Lily breaks up with Marshpillow, telling it that "we both knew this would end eventually".
