[James Corden:]

I'm just a Batman

I'm looking for some Pop Rocks

Something that's sweet inside

You look like the right fun size

[Niall Horan:]

Got done up piratical

To come here for this visit

Girl, when you break me off a Kit Kat

I'm gonna make your Tootsie Pop

[Chorus:]

If you're scary, let's do it

Give it, my Candy

My satchel's waiting

Trick or treat on it

[James Corden:]

I'm captain Sugar Daddy

Cuz I'm about to Starburst

Who's it gonna Jujube

I'll give it to you Good & Plenty

[Niall Horan:]

I love you now and later

Girl, you're just so Red Hot

You just gotta Charleston Chews

I'll crush your Candy 'til you say stop

[Chorus:]

If you're scary, let's do it

Give it, my Candy

My satchel's waiting

Trick or treat on it

If we're gonna get tasty, baby

I'll give you a Hershey's Kiss

Then a bunch of Swedish Fish

What's your Halloween fantasy?

You want a ghost?, baby Boo

You want a cow?, baby Moo

[Chorus:]

If you're scary, let's do it

Give it, my Candy

My satchel's waiting

Trick or treat on it
