The Ice King had fallen.

In north Scandinavia born and raised
On an iceberg was where you spent most of your days
Chillin' out maxin' relaxin' all cool
And all playin with some some penguins outside of the igloo
When one specific guy
Who was up to no good
Startin making trouble in your neighborhood
You got in one little fight and got really scared
And said "I'm movin' with the rats in my underground lair"

Today you are playing with a particularly feisty rat (which would make for an excellent supper), when suddenly a cat reigns on your parade. You think the cat is here to steal your dinner until it cries out, "Fionna! Moldyvort's gonna throat rape Fionna!"

It is clear your fanfic waifu is in trouble.
