Lammy (ラミー Ramī) is the lead guitarist of the band MilkCan and the main protagonist of Um Jammer Lammy. She has pale orange fur, dark blue eyes, small sheep ears, a dark brown circular nose, white horns and short red hair. She is normally a very shy, timid and otherwise sheepish girl who has trouble with various things and lacks a lot of faith in herself. The only time she isn't like this is when she has a guitar in her hands, where she becomes completely confident with a bold playing style.
