You did something strange and got into an accident again today. And 10 minutes later, you got a call from Ice King

Ice King: "FINN! There are a lot of people just like me!"

Of course your name wasn't Finn, I guess that stupid old man forgot your name again, anyway.You thought it was a novel bullshit, but when you reconsidered the accident you made earlier and went to the Ice Kingdom... Simon, Ice King, Ice Queen, Simom, Winter King, and many others...
