Finn and Jake have been teleported to Equestria by mysterious magic. They land in Twilight's Castle and things go bonkers from there! To a Ursa Major, a jerk of a Prince, some lovely love, and something that's way eviler than Ice King himself! That and more in Adventure Time: HIK! WAWIE!?! "Adventure Time, c'mon grab your friends, we'll go to very distant lands, with Jake the Dog and Finn the Human, the fun will never end, it's Adventure Time! Hey Ice King! Why're we Equestria!?! Can't believe you would do this! You giant Jerk! We're gonna travel across the land and find you, and we're gonna kick your ass! Yo, King of Ice, it would suffice, if you weren't such a jerk! We're gonna get to the bottom of this! And when we're done. Gonna kick your Ancient Booty!"
