Planet of the Apes refers to a 1968 film and the franchise that followed in its wake.
- "Return to Beneath the Planet of the Pigs" is a sketch seen in The Muppet Show: Sex and Violence which makes fun of the varying sequel titles in the film series. It is said to be the seventh release in its series. It stars an early Miss Piggy with beady eyes, as well as an early Dr. Julius Strangepork, known as Dr. Nauga.
- Excited about Birdnardo Birdolucci coming to Sesame Street in Episode 2575, Gina lists a number of films he's directed including Planet of the Eggs parts one and two.
- In episode 205 of Muppets Tonight, Ernst Stavros Grouper tells Kermit that he's now to be known as Virgil the Monkey because monkeys test better with audiences. He justifies the order saying that no one's ever heard of "Planet of the Frogs" (suggesting a connection to Kermit's new monkey designation and their primate cousin apes as seen in the film series).
- In the Sesame Street computer game Ernie's Adventures in Space, a bunch of grapes appear floating in space. One grape exclaims to another, "Get your stems off me, you green, seedless grape!" This references the famous line from the film.
- A status update on the Muppets official Facebook page claimed that they had several ideas for The Muppets spoof trailers, including "Rise of the Planet of the Prawns" (referencing Pepe the King Prawn and the recently released Rise of the Planet of the Apes). The trailer was subsequently released on Blu-ray without the Prawns reference.
- During an interview with MTV News, Kermit complimented Caesar's performance in Dawn of the Planet of the Apes, saying "I thought we could meet up and talk shop. Turns out he’s only computer generated."
- In a January 8, 2016 tweet, Kermit the Frog tweeted, "In my downtime while #TheMuppets is on hiatus, I've been working on some film pitches. So far I have ten pages on #PlanetoftheFrogs."  Fozzie Bear responded with two suggestions for taglines, which Kermit liked.
