The character models Sticky Fingers, Batty, Frogman, Hisser, Lavaman and Leo were designed by Harry Sabin.
The Tracker's character model was reused from the Cavern Monster as seen in Reign of the Monster (1983).
The character model used for the blacksmith was originally used as Garn in A Tale of Two Cities (1983).
The ship that the Space Pirates use is almost identical to The Keeper's ship in The Heart of a Giant (1983).
