Dice's monkey climbs out the window, but later when Sam and Cat arrive back home, there are cobwebs covering the window.
Dice said he doesn't like doing anything illegal, but he had no problem with getting Sam outlawed candy.
In most of the episode, Clarice(in doll form)'s emotion kept changing, for example when Sam and Cat just found out that Clarice may have turned on the TV, she had a normal emotion, yet when Sam says "and turned on the TV", she had a big smile on her face.
Sam mentions that since she was five years old, every Halloween she fills a big pumpkin with chili, eats the chili, unbuttons her pants and watches TV. However, in the iCarly episode, iScream on Halloween, she did nothing like that, but it's possible she did it after the webshow.
