 Until the late 1960s, many of the sets representing the interior of  the Nautilus were used as an attraction at Disneyland. This included  the chart room, the salon, with organ, and one of the observation  windows. The squid from the movie was fastened over the observation  window and was animated so that the beak would emerge, snap several  times, and then retract. When the building housing the 20,000  Leagues display was needed for a newer attraction, the sets were  removed and many were destroyed.
