Volume 1, Episode 17: Cleo takes credit for Ghoulia's killer project and crowns herself queen of the mad science fair. Find out how Ghoulia gets the last ghastly laugh!
Frankie and Lagoona walk through the gym, checking out other students' projects at the Mad Science Fair. Exhibits they pass by include a replica volcano with creatures inside and a tank containing a tentacled creature, which snatch away a geeky student. None of those can match the giant, pro-environment contraption that turns trash into "clean, green fuel" they notice next though. Frankie and Lagoona do not doubt this is Ghoulia Yelps's science fair entry, but Cleo shows up to 'correct' them, claiming it's her project. She clearly does not know what the machine is or does, but goes on to say it will make her the queen of the Mad Science Fair. She gestures toward a pink, shell-encrusted chair atop a column covered with a large piece of cloth, claiming it will be her throne. Lagoona attempts to tell her it's not a throne, but Cleo refuses to listen.
The girls find Ghoulia, who is paradoxically standing in front of a rather pathetic-looking project titled "The Effects of Water on Toilet Paper." The girls realize that Cleo forced Ghoulia to trade projects, something Ghoulia is obviously not happy about. They are outraged and tell Ghoulia to stand up for herself. Ghoulia just shakes her head sadly.
Meanwhile, Headless Headmistress Bloodgood awards Cleo the first place trophy. The girls comfort Ghoulia as Cleo rushes by, climbing up the column to the pink throne. As Cleo sits down with pride, Lagoona reiterates that the chair isn't a throne and reveals that it is actually her science project: a rehydration chamber. By pressing a button, the pink chair is dunked into the column of water underneath the cloth, soaking its occupant. Feeling that Ghoulia is entitled to a little payback, Lagoona offers the controls to the rehydration chamber to her friend, who eagerly presses it, dunking Cleo. And again. And again. And again. Frankie smiles, saying that she hopes Cleo is wearing her waterproof mascara, because "this could go on all day."
- Lagoona's rehydration chamber, minus chair, is her Hydration Station, which would see release in toy form in June 2011. The Hydration Station reappears in "Varsity Boos" as a regular tank and finally properly in the 2011 TV special "Fright On!", both times without chair.
- Frankie's eyes and cheek stitch and Lagoona's flower are switched when the two are taking a look at a volcano project.
