The Adventures of Rocky and Bullwinkle and Friends is packed with references to the original series (owing to the designer being a fan), including the Moon Men from "Jet Fuel Formula", the football game between Wossamotta U. and the Mud City Manglers, and the Fractured Fairy Tales version of "Sleeping Beauty" and Prince Darling.
For the former, Dennis Nedrys Ah-ah-ah! screen shows up as the tilt warning, and using the ball save occasionally prompts a female voice to say "I think we're back in business!" (a quote from Ellie after restoring the park's power).
For the latter, there's the use of a T. rex toy that moves around and eats the ball (on higher-tier versions, at least), the "Smart Missile" feature (albeit in name only), the CHAOS Spelling Bonus, and the phrasing of "Raptor Tri-Ball" (originally an attempt to write aroundWilliams Electronics' trademark on the word "multiball").
While the playfield being covered with imagery from the show is normal for Licensed Pinball Tables, the lights used for the two seasons' modes subtly incorporate imagery from each: season 1's are wrapped by Christmas lights (like the ones Joyce sets up in her home), while season 2's are placed on top of Will's scattered drawings of the Mind Flayer's tunnels.
Gromflomite Battle Multiball is based on a scene from the series' pilot. The instruction card (written in-character as Rick) further alludes to it by referring to the aliens you kill as "robots" in the original episode, Rick tells this to Morty as a means of getting him to shoot them (which is almost immediately disproven).
Getting a tilt warning leads to the game displaying a plumbus inside the cabinet being jostled.
The megaseeds are taken straight from the pilot episode, as is the implication that they're being stored in an unsavory place getting enough of them to get onto the high score board leads to the player being honored for their "Superfluous Butt Capacity".
