She wanted to use the book to go back in time and prevent Simon from becoming Ice King and possibly even stop the Mushroom War. In " Skyhooks II" when Betty gained all the gems from Finn, she got too carried away.

Throughout the Elements miniseries, Betty Grof uses the spells in the book in order to fix Ooo. Jake said that the book was destroyed but Finn revealed that during the events of " Crossover" he brought the Farmworld's Enchiridion back with him to their timeline. In order to do this the gems from the 3 elemental princess' crowns need to be inserted into the book. In " Winter Light" Betty Grof needed the Enchiridion to fix the Land of Ooo from the four elements. Due to the possibility of destruction to other dimensions, Prismo sent Finn and Jake to Farmworld to stop them. In " Crossover," Farmworld Finn and Farmworld Jake (Possessed with The Lich's spirit) used the Farmworld's Enchiridion to build a portal to the Multiverse. Although, this is merely part of Ice King’s fan-fiction, and isn’t in the actual continuity. Ice King then stole the real book and gave it back to Fionna. However, it was actually a bomb disguised as a book. In " Bad Little Boy," Doctor Prince stole the Enchiridion and tossed it back to Fionna. It opened the portal as soon as it was broken. It was later destroyed by Finn by having it bashed against his knee. This is done by turning the sword on the front of the book to the right and inserting the nine gems of power into their appropriate slots.

In the episode "The Lich" the book is shown to have intense magical properties, allowing a user to be able to have access to all of the multiverse's many dimensions. Later, Finn gives it to the Bear so he can learn to be a hero, but it is soon revealed that the reason the Bear took the book was to give it to the Snail - who was being possessed by The Lich. Its next appearance was in " In Your Footsteps." Finn used it to knock the food out of the Bear when he was choking. The book makes another notable appearance in " Another Way" in which Finn reads about magical Cyclops tears while the Clown Nurses are healing his broken foot. It first appeared in the episode " The Enchiridion!" in which Finn passes a series of trials to obtain it.įinn kept the Enchiridion, and it subsequently appeared in the episode " Evicted!," when he threw it at a worm on his bed. After the war, the Hero's guide somehow ended up in the hands of Key-per at Mount Cragdor, guarded by Mannish Man the Minotaur. The book was discovered by archaeologist Simon Petrikov ( Ice King) sometime before the Mushroom War in the Hindu Kush mountain range in Pakistan, as revealed in a newspaper clipping in " I Remember You." After he found it, he presented it to a museum.
