The action in this installment confirms the fact that The Adventures of Hoppity Hooper takes place in the same "reality" as The Adventures of Rocky and Bullwinkle (later known as The Bullwinkle Show). Earlier in the series, Hoppity had made mention of the Rocky and Bullwinkle characters, but more in the context of them being a fictional pair of friends.
The appearance of Dudley Do-Right confirms that Hoppity Hooper took place in the same "reality" as the cartoon Canadian Mountie's program.

The humanoid "mole people" living below the "diamond mine" can dig with amazing speed but constantly run into one another because they are blind.
In his search for a star, Waldo mentions that Foggy Bog is limited by the fact that its population is composed entirely of 617 senior citizens.
In order to evade the law, Waldo (a fox) somehow convinces Hoppity (a frog) that he is Hoppity's long-lost uncle. Hoppity will go on to call him "Uncle Waldo" on many occasions. Waldo also shows a trademark difficulty in remembering Fillmore's name, often substituting other names when addressing him.
