info
In "Little Dude" the hat became enchanted when it touched the flower of a buried Magi.

As Finn and Jake are getting ready for bed, the Magi climbs to the roof of the Tree Fort, but Jake says that it's probably just Ice King. The Magi then gets in the house by way of a broken window, but Finn and Jake catch him. The Magi then explains that the hat was evil, as is anything he touches. BMO tells them from upstairs that the hat got away and went to the Candy Kingdom. In the Candy Kingdom, a Candy Person walks into an alley when Finn's hat jumps on his head and warps his body into a grotesque, muscular form. Soon, Finn, Jake, and the Magi come looking for Finn's hat. They find the hat, which soon starts to fight them, throwing horses, trash cans, flagpoles and Candy People. One of the projectiles hits a Gumball Guardian which then alerts everyone of the evil presence. Little Dude then climbs up and possesses the Gumball Guardian, who then starts breathing fire and firing lasers at the Candy Kingdom. Finn and Jake convince the Magi to use his powers to help them, but he refuses and says he only turns things evil because he is always thinking about how mean his father was to him. Jake then convinces him to think something positive. The Magi then starts thinking about his mommy, who showered him in love, and begins giving life to objects that then wanted to give hugs. He then orders the objects to capture Finn's hat and they soon succeeded. Afterwards, he takes back all of their life energy. Finn feels sympathy towards his hat and asks the Magi to bring him back good. The Magi does so and Finn tells his hat that the Magi is his father, and tells the Magi to take care of his hat. Finn tells Jake that he needs a new hat, Jake replies "Okay, lets go skin an evil bear" and they walk away.
