Oni Press and Warner Bros. Discovery Global Consumer Products have unveiled Adventure Time: The Bubbline College Special #1, a massive 56-page one-shot featuring Princess Bubblegum and Marceline.

The press release follows:

Media Release -- It's... ALTERNATE UNIVERSE TIME! Oni Press, in partnership with Warner Bros. Discovery Global Consumer Products, is proud to announce ADVENTURE TIME: THE BUBBLINE COLLEGE SPECIAL #1 – a giant-sized, 56-page spectacular starring Princess Bubblegum and Marceline (together: "Bubbline" – get it?!?!) coming this August from Eisner Award–winning cartoonist and breakout star Caroline Cash (PeePee PooPoo)!



"I've been a fan of the show since it came out," said writer and artist Caroline Cash. "I remember watching it when it premiered on Cartoon Network. I think I was 14 years old? It completely shaped my comics making career as well, the first comics I read (outside of manga and newspaper comics) were by people who worked on Adventure Time. Since the show ended, I didn't think I would ever have a chance to work on anything Adventure Time related, so this has been a bit of a dream come true.

"I was in the tumblr trenches fighting for my life at 15 when the What Was Missing episode dropped and was a part of the Bubbline speculation in real time," continued Cash. "I remember when Marceline's voice actor said they were ex girlfriends... I watched the Stakes series in college with my friends who also grew up with the show... again it is crazy to me that I have been given the opportunity to add to the canon of them being in love in every universe... favorite couple forever... an OTP dare I say…"

"For years, Princess Bubblegum and Marceline have been the Couple of All Time (yes, capitalization required)," said Adventure Time Editor Megan Brown. "We're so incredibly excited to explore a fun, alternate universe romp with these—dare I say—utterly iconic sapphic soulmates, created by the deft and talented hand of writer/artist Caroline Cash. This comic is unapologetically queer, and we are very excited to get to answer the age old question: what would Bubblegum and Marceline be like in college…?"

Experience all the fun of college (and none of the stress) in this giant-sized comic spectacular starring Princess Bubblegum and Marceline! What, do you think Ice King should get to have all the fun?! Heck nah! Fanfics are cool and all, but you know what's even cooler? Peering into alternate universes—and Prismo's got the perfect one in mind . . . Princess Bubblegum has just started school at Ooo University (double majoring in chemistry and princess, of course!). But between difficult roommates, overreaching bodyguards, assassination attempts, and—more importantly—a full class schedule, will Bubblegum be able to survive her first year in college?! With the help of one super-cool, super-mysterious flying vampire who she is mayybeee falling in love with, it shouldn't be all that hard. Turns out Marceline and Bubblegum are made for each other in any universe!

BECAUSE YOU DEMANDED IT! Eisner Award winner Caroline Cash presents the giant-sized, self-contained, alternate-universe, super-sweet one-shot you've been dreaming of (and posting about) – starring Princess Bubblegum and Marceline as awkward, overachieving, possibly smitten college students just trying to make it through freshman year! Featuring covers by Caroline Cash, Robyn Smith (Nubia: Real One), and Chloé Stawski (Sapphic Pulp), declare you major and come back to school when ADVENTURE TIME: THE BUBBLINE COLLEGE SPECIAL #1 hits stores on August 20, 2025!
