《Happy Halloween》的歌詞是：
Happy Halloween, everybody!
Trick or treat, y'all come back!
Spider on my head, yikes!
Grab your bat and say, 'Boom!'
Goin' up the street, to see my friends
Gonna play some games and eat some fun
Candy and a treat, what a treat!
Everybody happy, happy halloween!
Happy Halloween! Happy Halloween!
Come on out and play, everyone!
Happy Halloween! Happy Halloween!
Yeah, yeah, yeah, yeah!
