Ble (or BLE) is the name of a comic series that has appeared in multiple episodes of Adventure Time, including the comic. Finn reads it at the end of the episode "Marceline's Closet" while lying on his bed. In "Incendium," when Jake searches through his pack for a gift for Flame Princess, one of the items he pulls out is another issue of Ble. Like the rest of the items he pulls out, it turns to ashes due to the intense heat of the Fire Kingdom. Another issue of Ble appears in the episode "In Your Footsteps" in Finn's pack.
The cover varies by issue. The first one 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 humanoid wearing only blue shorts. His legs look very small compared to the rest of his body. The word "HEY" appears at the top. Jake's issue in "Incendium" features the same cheeseburger floating in space near colorful planets and a sun.

It may not be part of the same canon or continuity as the animated series.
In Issue 3 of the Adventure Time comics, on the last page of the story issue 3, Breakfast Princess is reading an issue of Ble. The cover has a face instead of the cheeseburger that appears on the last two issues.
