S9E4: Halloween on Spooner Street
Hey, Stewie, you all set to go trick-or-treating?
Whoa, what the hell are you doing?
We're under attack, Brian!
By zombies and vampires and a Mexican princess!
Stewie, those aren't monsters, they're kids.
Yeah. It's what kids do on Halloween.
They dress up in costumes, and they go around asking for candy.
