Marvin is the owner of Marvin's Music City. He participated in a sketch with Simon Soundman. In this sketch, Simon wants a trumpet, but he makes a trumpet sound, making Marvin confused. He brings a violin, a small piano and a drum. When he finally understands, he brings the trumpet. After Simon pays and leaves, Marvin says that he should have asked him if he wanted to join his band, but he makes all the instruments' sounds instead of saying the word "band", revealing that he too can make sounds with his mouth.
