• In other episodes, Russell can hold his breath underwater, considering that he is a sea otter and has done so in other episodes. In this episode, however, he requires air pumped into a diving suit. This could, however, simply be because he was underwater for a prolonged period of time in this episode. The fact that he had to go to a greater depth also supports the explanation of the diving suit.
    • This can be also explained by the fact that the writers needed to have Russell wear that diving suit in order to have this death scene in this episode.
  • The featuring characters in this episode would all later star in A Vicious Cycle, along with Flippy.
