Um Jammer Lammy

Um Jammer Lammy is a rhythm game developed by NanaOn-Sha and published by Sony Computer Entertainment for the PlayStation in 1999. It is a spin-off of PaRappa the Rapper, with art by Rodney Greenblat.

Lammy, the nervous guitarist of the band MilkCan, has to get to a gig and faces a string of odd situations on the way, each played as a song. The player presses buttons in time with a teacher’s guitar lines, and PaRappa is playable after the story is finished.

A native PC port made by static recompilation is available as a build kit.
