On the night of Halloween Adventure Time characters refer to completely different characters. They really are cruel monsters, but it does not prevent them to solve puzzles and to exercise their intellectual abilities. Visit the ancient castle, where you will pass the real brainstorming that can develop your attentiveness. Before you will be a lot of pieces dedicated to the holiday. Sometimes they will be repeated, because you need to collect the same by means of the gun, which is charged exactly the same objects. Shoot exactly the same, and if they match three of the same ball, they will disappear and you'll get your prize.
