Dress like Finn the Human Costume | Halloween and Cosplay Guides
What time is it? Cosplay time! Their outfits are almost identical, except instead of paling around with Jake the dog, you can carry a cute stuffed Cake the cat with you. If you want to look totally mathematical, get some of your friends to dress up as Adventure Time characters with you. Showing up at a convention or party with Princess Bubblegum and Lumpy Space Princess will be a huge hit. Bonus points if you get someone to be Ice King.
