The Staring Horse has only been seen in the episode "The Eyes." Finn and Jake spend the episode trying to fall asleep after a full week of hard work, but can't because this horse is staring at them through their treehouse's window from a nearby hill. At the end of the episode, the Horse is revealed to be the Ice King in disguise. Finn and Jake said that the horse has wacked-out poo brain. It makes a cameo in "Princess Cookie," when a banana guard disguises himself as one.
