I don't get the scene in the Cloning Chamber *SPOILERS*

[Trancua]

The one with Sam's clone, Skunkape, girl Stinky and Flint Paper.

So there's Flint, kicking butt while apparently explaining Stinky's plan to Sam. He mentions all sorts of stuff, image projectors, fog machines, granite, and even says that Stinky wasn't created by old man Stinky, but is actually a mermaid or something.
Needless to say, all of that flew right past me.

Would someone care to illuminate me in that matter?

According to Flint Paper, Stinky is a mermaid, and the whole ordeal involving the cake of the damned from Season 2 was a hoax created by Girl Stinky (the cake itself being created using a fog machine and a projector, a feat possibly alluding to similar scenarios in Scooby-Doo) to fool her elder counter-part, for whatever reason.

However, Flint's credibility is somewhat spotty mostly due to his tendency to exaggerate, although she is definitely a mermaid, already hinted by her fish apron, several nautical items on her person, and minor hints she has dropped. Additionally, Charlie Ho-Tep refers to her as the "fish woman."
