Let's take stock of this situation. There are security guards. A boy wearing a large cocktail shrimp on his head. Some kind of zombie-pirate (armed to the teeth in case of wayfaring vampire-ninjas), and a tubby cat dressed as Super Grover.

Obviously, the security guard is a dog person.

AH-HYUCK~

Heathcliff dresses up as a crustacian in an effort to trick random Fish Market owners into thinking that they've purchaced the largest lobster ever. Upon being thrown into a pot of boiling water, Heathcliff realizes how stupid he was, just in time for the Fish Market people to notice that the lobster is really a poorly disguised cat. Both parties part, extremely pissed off at each other.

Heathcliff thinks that he has gotten an awesome pizza, because the sign on the door says "NEW." The pizzeria people that Heathcliff out earns by being a fat fucking cat think that they've done an awesome job of getting rid of old pepperoni. If it only took one pizza to clear up the old pepperoni, they probably didn't have a need for "NEW" toppings, but then there wouldn't be a joke. Couldn't go without the jokes.
