Pops' Harpsichord is seen in "Mordecai and the Rigbys", and mentioned in "House Rules". During the scene, where Mordecai and Rigby go to Pops for music advice, it is shown Pops playing the harpsichord. You can hear the notes that he is playing. In "Fists of Justice", the harpsichord apparently gets stuck in the doorway, so Mordecai and Rigby ask Skips to help move it. However, Skips can't even move it so in the end, as a favor for Mordecai and Rigby saving The Guardians of Eternal Youth, two of the Guardians help move it out and in fact, succeeded.
