Ble

Ble (or BLE) is the name of a book/comic/magazine that has appeared in multiple episodes of Adventure Time, including the comic.

Finn was reading an issue of Ble at the end of the episode "Marceline's Closet" while lying on his bed. The cover shows a cheeseburger with no arms that seems to be drooling, since there is a liquid on the floor and its tongue is sticking out. At the back of the book is a muscular blond-haired person who looks like a human, but is probably a humanoid. He is only wearing blue shorts. His legs look very small compared to the rest of his body. At the top, it says, "Hey." The pages of the book looks like a bunch of pictures so it's probably a comic or a magazine.

In "Incendium," when Jake was searching through his bag for a gift for Flame Princess, one of the items he pulled out was another issue of Ble. Like the rest of the items he pulled out, it burned into ashes.

In Issue 3 of the Adventure Time comic, on the last page of the story "Bacon Fields", Breakfast Princess can be seen reading an issue of Ble. The cover did not have the cheeseburger that has appeared on the last two issues, but instead, a face.
