She decides to never sing 'Witching Hour' again.

Deuce expresses anxiousness towards being surrounded by Cleo's high class family,who he knows do not like him. Cleo assures him that she is not embarrassed of him and their love is unchangeable. Cleo invited her ghoul friends, Clawdeen, Draculaura, Catty, Operetta and Frankie to go along with her and Deuce. In Boo York, the De Niles meet with the Ptolemy family. Cleo is annoyed with Deuce's informal greeting to Madame Ptolemy, and that he wore headphones with rap music on during the meet-and-greet; much to the Ptolemys' disdain. The next morning Nefera and Mouscedes host a brunch for the everyone,except Deuce is missing. Cleo listens to Seth Ptolemy's poetry, and nearly falls asleep from boredom. She is angry when Deuce arrives in swimming wear, and has to borrow an oversized coat to enter the brunch. Cleo is unaware that her sister is setting Deuce up to look a fool; Cleo is furious when Deuce's shenanigans necessitate firefighters.

Later that day Cleo looks through dresses to choose for the night's gala. She is in better moods towards Deuce when he arrives, though he is miserable after everything that's happened. He tells her he's realized how unworthy he is to be dating an elegant princess and says the right thing to do is break up. Cleo passionately disagrees but Deuce determinedly throws the Egyptian chin ornament she'd given him into the fire place. He leaves Cleo with a broken heart and tears.

We next see her in the hotel room, alone, crying. Nefera comes in to see if she's ready for the gala (and to gloat), but is shocked when Cleo screams that she isn't going without Deuce. Nefera then pontificates to Cleo about her family name to convince her to buck up and forget him (and also to protect her designs on the crown); after which Cleo resolves to go, and deletes the photo of her and Deuce she took that day.

Generation 2


Cleo's first generation 2 webisode appearance is in her bedroom, hosting her very own talk show! She also has the best possible guest to interview... herself! Cleo switches personas between "hostess" and "guest" by switching chairs and donning or doffing her glasses. During the interview, Cleo tells us that she's 6000 years old, her father is Ramses de Nile "of the Egyptian De Niles", and she just spent about a millenium in a tomb. She also tells us about Draculaura taking her to Monster High, and the new friends she's made: Draculaura, Clawdeen, Frankie, Lagoona, and Ari. Cleo - Meet the Ghouls

TV Specials

Cleo is the first monster Draculaura, Frankie and Clawdeen find with the Monster Mapalogue in her pyramid tomb. True to herself as always, she brings up a personal chef and masseuse after being told the new school has all the essentials. Despite the ghouls shaking their heads no in unison, she still befriends and tours along with them, also finding Lagoona Blue and Deuce Gorgon through the Mapalogue (and getting accidentally rocked out by the latter). Later, when Moanica D'Kay and her horde of zomboys attack the ghouls, she helps fight them off with the use of her wraps. This ability also comes up later on the dance floor. Welcome to Monster High

Generation 1

Generation 2


  • In the original version of Cleo from Generation 1, in the webisodes, she has the right part of her halter top in her 'Basic', 'Signature' (which the side is also acknowledged as the "left-hand" side) crossing over to the left side (also acknowledged as "right-hand side"), just like the doll series of her 'Basic' doll assortment of " 'Signature' outfits". But in the webisodes, when she is facing the left-hand side of her body, her body turned to the right side, it literally looks like it is on the other side, up until the late Volume 3 webisodes. In the CGI TV specials, the right-hand side halter strap instead crosses over to the other side, unlike the doll, properly for creative license or "artistic license".
  • The 3D TV specials has Cleo's 'Basic' halter top with more glitter than what it appears as in the original 2D animation and webisodes, closer to the doll line.
  • In the computer-generated, computer-animated, 3D TV specials, the nail polish color of her 'Basic' appearance is not light purple, but instead deep red that looks almost black. This was the nail color for Frankie's original 'Basic' look.
  • The Volume 5 lining made Cleo's hair much straighter to keep in line with being more accurate to the doll line, and without the "bottom swoop" or bottom curl.
  • In the original reboot Signature series of Cleo, she now sports almost-solid-black hair with streaks of real gold rather than black hair with light brown streaks and gold streaks.
