Olaf the Red is a huge, beefy, tuba player. He provides some bass note accompanyment to the cacophany of banjos that make up the bulk of the musicians. Olaf always brings his tuba on the field with him, often using it to bash other players with... his tuba is colored brass, but it's made of steel and he sharpens the edges of the bell so it will cut deeper. He's still trying to figure out a technique for intercepting the ball with his tuba, though.
