HBO Max has given a straight-to-series order for a new 10-episode animated spinoff, “Adventure Time: Bubblegum and Marceline.” The series centers on characters from the long-running “Adventure Time” franchise, focusing on the fan-favorite pair often referred to as “Bubbline,” represented by Bubblegum and Marceline. Multiple outlets report that the order was announced in conjunction with industry events at Annecy. The production is handled through Cartoon Network Studios and is described as a franchise expansion beyond earlier “Adventure Time” projects.

Deadline also identifies the show’s creative leadership, noting it comes from “Adventure Time: Fionna and Cake” and “Distant Lands” showrunner Adam Muto. Across coverage, the key detail is the same: HBO Max renews the franchise with a new, character-driven spinoff that is set for a 10-episode run under the straight-to-series model, meaning production and development begin based on the series commitment rather than only a pilot.
