"Monster Party" is the 27th episode of Season 2 of OK K.O.! Let's Be Heroes and the 79th episode overall. It is a Halloween episode that features characters from Scooby-Doo and the Ghoul School.

Official Synopsis

Enid is faced with a choice when her old friends from Ghoul School show up.[1]









  • The end credits show the original Ghoul School girls' model sheets displayed one by one.
  • Phantasma's, Elsa's, and Sibella's voice actresses reprise their original roles from the Scooby-Doo and the Ghoul School movie. Winnie's original voice actress passed away on January 7, 1988, from liver cancer and Tanis' original voice actress retired.
    • Oddly enough, Natalie Palamides and Kristen Li both voice Buttercup and Bubbles respectively in the 2016 TV series of The Powerpuff Girls.
    • This was the last time Russi Taylor reprised the role of Phantasma before she passed away the following year on July 26, 2019.
  • This episode was released in the same month as "Scooby-Doo and the Ghoul School" which came out 30 years ago on October 16th, 1988.

Production Notes

  • From the What A Cartoon! podcast, the writers wanted to do a story where a character comes out to their friends and that the friends became cool with who the character is.[2]
    • The story aspect was able to give a double meaning behind the message in which Enid came out as a ninja to her friends and the other meaning is the concept of people coming out of their sexual orientation or their gender identity.
  • Ian Jones-Quartey shared an image of this episode on Twitter, and said that it would be released by October, however, he did not state the episode's name.[3] The name was later to be revealed as "Monster Party".
  • Ian Jones-Quartey loved this episode because he and the crew got to see the original model sheets for the Ghoul School girls.[4]


Cultural References

  • During the scene where K.O., Boris, and Icky pop out of the jar of ashes, the picture in the background is a silhouetted version of the cover of the original Castlevania.
  • During the flashback sequence, Grim from The Grim Adventures of Billy and Mandy is seen on "Teen SCARE!", a magazine which Phantasma is holding as she comments "Oh man, the Grim Reaper is so hot! Wouldn't it be the absolute best to grow up as spooky as this Enid? I can't think of anything cooler!" (Enid instead looks down at issue 8 of "Hot NINJAS"). The cover is subtitled "THIS YEARS 20 HOT GHOSTS".
  • During the scene where Winnie asks if anyone wonders what happened to "that weird guy and his Great Dane" was a direct reference to Shaggy Rogers and Scooby-Doo, the two main characters of the Scooby-Doo series and the main characters in the original film Scooby-Doo and the Ghoul School where they act as gym teachers for the girl's volleyball team.
    • Elsa even pokes fun at Shaggy's speech pattern, stating how he "talked, like so weird, man".
    • Enid even says "ruh-roh" similar to Scooby-Doo.
  • The scene where Enid places a spell on the tree, The phrase "lorem ipsum dolor sit amet" refers to a commonly used Lorem Ipsum placeholder text used to demonstrate the visual form of a document.
  • The scene where Elsa, Phantasma, and Sibella want Enid to stop the tree had the three resemble the Eds from Ed, Edd n Eddy, complete with the Squigglevision-esque vibration.
    • Elsa resembled Ed, Phantasma resembled Edd, and Sibella resembled Eddy.
      • Character designer, Julia Srednicki stated that the reference was made by Stevie Barbolla.[5]
        • Ian Jones-Quartey then later on explained that in the first pitch, Stevie kept drawing Elsa to appear more like Ed to make everyone in the room laugh. He mentioned that in one of the rules of the show is that, "if it gets a laugh, it stays in". However, they had to make a new design model sheet and inking guide for the animators and Ed's mouth chart since they did not have access to any of the original Ed, Edd n Eddy designs.[6]
  • The scene where Bernard turns human parodies the transformation scene from Disney's 1991 animated film Beauty and the Beast.
  • The rap that Rad sings at the end is a reference to Scrappy's rap at the end of Scooby-Doo and the Ghoul School.
  • The episode's title may be referring to the 1989 NES game Monster Party.
