Trivia

General

• This episode was initially titled "Funbelievable."
• This episode's title is a portmanteau of the words "fun" and "unbelievable."
• This episode was set to unofficially debut on Nickelodeon on July 2, 2023 at 7:45am, but it was quickly shafted for a rerun of "King Plankton," likely being a scheduling error.
  • This would make it the fourth Nicktoon episode to be scheduled for an accidental early debut, following The Fairly OddParents' "Freaks & Greeks," The Patrick Star Show's "Who's a Big Boy?," and SpongeBob's own "My Friend Patty."
    • Out of all of those premieres, only the first made it past the airwaves.
• This episode was originally scheduled to premiere at 1:00pm, but was moved to 5:00pm.

Cultural references

• When Baby Prunes says "Hey, you, get off my cloud!," she references a quote from Hotel Mario.

Episode references

• Sandy holds the world record for holding the most nuts in her mouth, possibly referencing the events of the episode "Squirrel Record"; however, in that episode it was revealed that all of the records Sandy broke were from a book that was 30 years old.
• Nosferatu's castle and vampire form, as well as Slappy's ability to disjoint his head return from "Squidferatu" and "Slappy Daze," although bat Nosferatu is not traditionally animated like in his first appearance, instead featuring his head plastered over animated wings.
• Baby Prunes' aggressive attitude and thirst for thrills return from "Biddy Sitting," putting Rube in danger by almost diving a plane straight into the ground.
• Old Mrs. Perkins returns from The Patrick Star Show episode "The Drooling Fool," at war with Baby Prunes over who's the oldest town resident. She later proves herself right, turning to dust after their lengthy battle.
• Rube had previously interviewed Baby Prunes and her daughter in The Patrick Star Show episode "Patrick's Got a Zoo Loose," which also featured an appearance by Nosferatu and Slappy.
