Um Jammer Lammy (ウンジャマ・ラミー, Un Jama Ramī) is a rhythm video game developed by NanaOn-Sha and published by Sony Computer Entertainment for the PlayStation video game console in 1999. It is a spin-off follow up to 1996's PaRappa the Rapper, once again featuring the collaboration of music producer and game designer Masaya Matsuura and artist Rodney Alan Greenblat. An arcade version co-developed by Namco, titled Um Jammer Lammy Now!, was released for the Japanese arcade cabinets in December 1999. The game received generally positive reviews from critics.
