an evil heart beast, and then slay an "unaligned" ant. Finn kills the beast, but refuses to kill the ant, leading to him defeating the being. Finn is then confronted by Mannish Man, the keeper of the Enchiridion, who gives Finn the book. Finn's first act is to read a chapter about kissing princesses. Production "The Enchiridion!" was the first episode of the series produced for Cartoon Network. Frederator Studios had pitched an Adventure Time series to Nicktoons Network, but the network passed on it twice. The studio then approached Cartoon Network. The network said they would be willing to produce the series if Ward could prove that the series could be expanded into a series while maintaining elements from the original short. Ward, with help from Patrick McHale and Adam Muto, turned in a rough storyboard that featured Finn and an "oblivious" Princess Bubblegum going on a spaghetti-supper date. However, the network was not happy with this story, and asked for another. Ward then created an early storyboard for the episode, "The Enchiridion", which was his attempt to emulate the style of the original short. Cartoon Network approved the first season in September 2008, and "The Enchiridion" became the first episode to enter into production. Because it was the first episode of the series made, the episode originally was twice as long. During the scene in which Princess Bubblegum tells Finn about the Enchiridion, the original storyboard featured an even longer sequence of Bubblegum detailing the history of Ooo and its heroes. Because it was largely unneeded, it was cut out. The first draft of the storyboard featured Finn encountering twelve trials, which included making friends with a giant bat, dealing with a wizard gnome, and fighting skeletons. Because the episode was too long, these were cut out, and replaced by Finn stealing the giant's dollar. The episode originally was also supposed to have a scene featuring "this little tumor creature dancing behind these red velvet drapes that opened up in a knot in a tree." According to Ward, the red curtains were a deliberate nod to the "Red Room" from David Lynch's famous television drama Twin Peaks. However, the scene was eventually cut. Choose Goose was originally supposed to make his appearance in this episode, offering Finn and Jake some juice. The character was cut for time, but later reappeared in the second-season episode "Blood Under the Skin",
