Um Jammer Lammy is a rhythm-based music game developed by NanaOn-Sha and released for the PlayStation in 1999. It is a spin-off of PaRappa the Rapper, but instead of rap battles, it focuses on rock music and guitar-based rhythm gameplay starring a sheep guitarist named Lammy.
What is Um Jammer Lammy?
Um Jammer Lammy is a rhythm action game where players must press buttons in time with music while following on-screen prompts. The game follows Lammy, a shy sheep who must perform guitar-based music challenges to overcome everyday problems and stage performances.
The gameplay keeps the signature “call-and-response” rhythm style but replaces rap with rock music energy.

Players press controller buttons in sync with musical cues to simulate playing guitar riffs. Timing and accuracy determine performance quality.
