From the Super Mario Wiki, the Mario encyclopedia
"Heartbeat Skipper" is a special item in Paper Mario: The Origami King. It is one of four disks found within the Temple of Shrooms, each belonging to the DJ. It is found in a chest on a high ledge with a blocked pipe. Mario must walk through the open sarcophagus in the west wall of the room where the first faceless Toad is found. Here, there is a pipe with the other side blocked off, and a chest containing the record. Much like "Deep, Deep Vibes" and "M-A-X Power!", collecting this disk is not mandatory, as it is not able to lure Hole Punch out of its room. However, the record can still be given to the DJ and played, even after the correct track, "Thrills at Night", has been chosen. After listening to this track for a few seconds, Hole Punch describes it as overrated and overplayed, with a distracting high rotation and only a few good seconds.
