Hoppity Hooper

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.

Golf scores for "Ward," "Hayward," and "Turner" are announced in this episode, references to the last names of real people who contributed to the program's production.

One of Hoppity's messages sent back to the surface that reads "plant more beans" drifts to Congress in Washington DC and becomes the basis for new farm legislation.

The horse - named "Big Dud" - has a tendency to fall asleep on the racetrack during competition.

In a send-up of Hollywood versions of "Frankenstein," the citizens of Foggy Bog treat Fillmore as a monster when he maintains his giant vegetable form after returning from the "Traffic Zone."

In order to earn money to travel to the frog-jumping contest in California, Waldo gives away skis made from broken pickle barrel staves. When the citizens of Wisconsin injure themselves on these skis, he sells the pickle juice as a liniment.

This episode features the odd concept of a single ghost splitting into separate male and female spectres, almost by some kind of "mitosis."

Waldo becomes the "Chief Snoop" of his own "I-Spy Detective Agency."

Waldo decides to modify his old stand-by "Professor Wigglesworth's Indian Guide Elixir" into a new miracle women's skin cream called "Pack-A-Derm."

After Fillmore and Waldo have a fight and part ways, Waldo tells Hoppity that they were once a great team - like "Rocky and Bullwinkle."

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.
