  • The name of the episode is based on the movie "Joe vs. the Volcano".
  • There are several parodies of James Cameron's Titanic in the episode, but the most notable one is when Olaf's potato sinks into the sea of balls. However, the potato was saved after the balls drained back down.
  • Ms. O states that she has lost a lot of headquarters in the past due to various accidents.
