Everything single thing that Corvax does in the beginning of Lesson 3 screams "predator". He sits by his computer fantasizing about Sylvia, creates a virtual image of her body (labelled "The Body") while snickering "I've got you now", prints out and kisses a life-size image of her, and then creates a three-dimensional copy of her.
Fridge Horror: After Corvax gets demoted at the end of Muzzy in Gondoland, he ends up working in the kitchen... where he could have the opportunity to poison the royal family in revenge anytime (that is, assuming there was no royal taster). Fortunately, the idea never crosses his mind. Either that, or maybe because even he wouldn't go that far.
Nightmare Fuel: When the King attempts to fix Corvax's computer, he somehow gets trapped inside it. This stops the computer from creating more clones of Sylvia, but Muzzy has to find a way to get him out. Claustrophobia and technophobia invoked! Made worse in the 20-episode TV airing, when the scene takes place at the very end of one episode. The King vanishes, and the kids will wonder what happened to him until the next episode.
