Carly, Sam, and Freddie shoot their Halloween web cast from an apartment that is rumored to be haunted. When creepy things start happening, the friends worry that the ghost rumors just might be true. Meanwhile, Spencer forgets to buy Halloween candy, and he ends up giving children odd and random objects, which leads them to the point of rolling him down the ocean with him inside a giant pumpkin that he carved. During the show, Sam shows viewers how to pull Halloween pranks using masks.
