Final series appearance of Fenton Crackshell.
This was the last single-part episode of the DuckTales series.
Clips from this episode was prominently used in "DuckTales: The Movie Special", which aired about three months before the episode.
There are several references in the episode to Herman Melville's classic novel, "Moby Dick." Scrooge calls the whalelike computer glitch "Moby Glitch" and Fenton says "call me Ishmael."
This episode has a similar set-up to the TaleSpin episode "Bearly Alive", in which one of the characters misinterpret a call saying that one of the characters will die.
