In fact, it becomes a minor plot point in Sam's plan.
Sam's apparent addiction to root beer resembles stereotypical alcoholism.
Sam (yelling at Cat): I drink root beer because of you!
Again, a young girl is left alone with an adult man, this time in a shack in the middle of an empty cemetery at night.
Spanish is the vehicle used for getting this bit past the radar in a bonus scene during the credits.
Sam (at Cat): Si no encontramos nuestra piña llena de dinero tendré que agarrar las tijeras y cortarse los dedos de los pies!
Translation: If we don't find our pineapple full of money I will have to grab the scissors and cut off your toes!
Cat seductively asking Freddie if they want to hang out.
The two of them flirt in Spanish.
Robbie accuses Freddie of Fadoodling Cat all around Hollywood. Quite possibly the most blatant sexual reference on a Nickelodeon show follows:
Freddie: I didn't fadoodle with Cat!
Cat: You could have if you wanted to!
Jade kicking out the boys out of a table with just a stare. While the boys flee in terror with that very look, it looks more seductive and arousing than it is terrifying.
Considering what Jade finds arousing they have a good reason to flee.
After Sam kisses Robbie, she says sultrily, "That was some tasty Robbie."
After Cat locks Sam in a closet and dresses in a stunt outfit in order to jump the killer tuna in her place, Sam points out that people will recognize her since they don't have the same body type. This leads to Cat grabbing two oranges and stuffing them in her outfit, making her chest stick out. Right before she leaves, she says, "Yay boozums!". (Watch for the oranges after the bike wreck.)
Merf starts trying to shove his face up Cat's skirt.
Sinjin from Victorious kisses both Cat and Zoran on the forehead. Their faces after this are priceless.
They get this out of the way early on with Cat trying to soak apples in cranberry sauce. She calls them 'crapples'.
Cat: How's it taste? Sam: Like crapple.
You didn't think they'd be able to get a Silence of the Lambs homage past the radar in a Nickelodeon show? Think again! Dice is trapped in a deep pit and Nora (the "Psycho" in the episode's title) even screams at him "OR ELSE IT GETS THE HOSE AGAIN!" before throwing an actual garden hose at him.
