The Needles Piano is an instrument given by Marvin to the player in the Demo Area of Petscop 11, resembling a spinning purple triangular pyramid.

Marvin requests that the player "play music for baby[...]" and the object materializes, when the player picks it up a message, "PLAY NEEDLES PIANO NOW" flashes on screen. The player uses the Needles Piano to play music which Marvin calls "Lovely" but eventually the instrument's notes sour and the "piano" turns red, ending with Marvin telling the player to "do it better next time".
