This episode has several references to Star Wars including:
-The alien that confronts The Scotsman in the beginning is identical to the Rodian Species
-Before the Fishmen appear, The Scotsman says "I have a bad feeling about this" which is a famous line said in every Star Wars film
-When they reach the Sea Port, The Scotsman says "You will never find a more wretched hive of scum and villainy." This is the same quote Ben Kenobi uses to describe Mos Eisley in Star Wars Episode IV: A New Hope(1977)
-When they hire the ship captain to take them to The Great Unknown, their conversation is identical to when Luke Skywalker and Ben Kenobi hire Han Solo to take them to Alderaan in Star Wars Episode IV: A New Hope(1977)
