- Growing the Beard:
- Jim Henson felt this special marked the point where Kermit the Frog was finally a fully-developed character. Henson sometimes mistakenly said this was the first time Kermit was identified as a frog (that was actually around 1965), but Kermit as portrayed here is no longer the Deadpan Snarker hipster or Slapstick Comedy foil of previous years. He's now recognizably the intelligent, good-natured, mild-mannered Everyfrog that became so familiar.
- Muppet fans have also said this special was a big turning point in the history of the Muppet franchise. After the more overtly comedic Hey Cinderella!, The Frog Prince used more serious storytelling, along with whimsical moments and good production values, with the mix of humor and heart that would become the Henson trademark. Especially, Jerry Nelson's performance as Robin is praised as an early example of a Muppet with great emotional depth and complexity.

- Memetic Mutation:
- "Have a popover, froggy!"
- "Stay asleep, and let frog go."
- Retroactive Recognition: Gordon Thomson (the human Sir Robin) went on to play the villainous Adam Carrington in the original run of Dynasty. Trudy Young (Princess Melora) co-starred in the Cult Classic 1971 "Canadian hockey romance film" Face-Off as a hippie rock singer who strikes up a romance with a hockey star (a film that was later parodied on SCTV as Power Play).
