A what if "Elsa and Anna built a sandwich that night instead of a snowman."

At around noon that day, a young Anna knocks on Elsa's door and begins singing to her sister

Elsa
Do you want make a sandwich
C'mon let's eat one rightaway
We never seem to get them anymore

Cold cuts from a store
Or a hot one from takeawa-y

We used to make best Toastie
But now we won't
Since you began to insist on pie

Do you want to build a sandwich
It doesn't have to be a sandwich

Go eat a steak, Anna
Ok, fine

(Years later, Anna knocks on Elsa's door again.)

Do you want to make a sandwich?
With some rye, some pickles and some smaltz

I think some capicola would also do
I've started talking to
The lettuce and dijon

"Ham is also jamon"

It gets a little oily
Even with reubens too
To be served with a side of fries

Munch crunch
Munch crunch
Munch crunch

Elsa
Please, I know it's wei-rd
People are asking if you've eaten

They say have bolognie
And I'm trying to
Slice it thin

We only have ciabatti
It's a bread made from yeast
But it also takes long to che-w

Do you want to build a sandwich?

(More years later) Anna and Kristoff are stuck in the frozen woods together, they are taken by surprise by a giant sandwich named Olaf.

"Oh my god, it's a talking sandwich!" Anna yelps.

"Yes... yes it is," Kristoff replies.

"Kristoff?"

"Yes..." he repeats as he ponders, "it's a giant sandwich in a frozen wasteland which can't grow anymore... vegetation."

"Kristoff?" Anna asks to get his attention again.

"Quick, capture him, we can use him to feed everyone!"

"What?!" Anna says, alarmed with the idea.

Sven, the reindeer begins to huff at Kristoff too.

"Sven, it's the sandwich or livestock, your pick," Kristoff tells the reindeer.

The reindeer, along with Kristoff begins chasing down Olaf the sandwich.
