What's The Marceline GIF On Twitter? The Lewd 'Adventure Time' GIFs Enlarging Princess Bubblegum And Other Female Characters Explained
Internet users on Twitter / X are treading lightly this week, all because of a few lewd Adventure Time GIFs that show the female characters Marceline the Vampire Queen and Princess Bubblegum with enlarged chests.
The "Marceline GIF" and "Princess Bubblegum GIF," as they're simply being called on Twitter, have sparked a shock media trend on the app. Many users are referencing the GIFs without saying it outright, sparking confusion and perilous curiosity.
All of the NSFW Adventure Time GIFs seem to trace back to one Newgrounds artist, who went on a spree back in 2019-2020.
So, who are they? Where did the "Marceline and Princess Bubblegum Breast Enlargement GIFs" come from, and why did they go viral on Twitter this week? Let's explain.
Where Did The NSFW 'Marceline GIF' Come From?
The infamous GIF in question was created by an artist named YetiG on the site Newgrounds in 2019. We can't link to it here, but a quick trip to their page or Twitter account, @ShootUrGooMaDoo, will give you what you seek if you really wanna find it.
The GIF uses a scene from season 1, episode 12 of Adventure Time, titled "Evicted!" It's actually Marceline's first appearance on the show. In it, she comes to Finn and Jake's treehouse and claims that it's hers.
At one point, she's seen draining the jelly from a donut while leaning on a rainy windowsill. It's the clip that YetiG chose for their lewd imagination, which enlarged Marceline's chest to an unrealistic degree. Her breasts are seen breaking her tank top in the notorious Rule 34 fan animation.
Where Did The NSFW 'Princess Bubblegum' GIFs Come From?
YetiG has also created some similarly "extra-large" GIFs of Adventure Time character Princess Bubblegum (PB). One shows the pink princess walking with a tray. The other shows her turning around in an oversized top. Both went viral on Twitter this week.
Like the Marceline GIF, both were animated by YetiG back in 2019-2020. The artist originally shared them on Newgrounds and Twitter, where they generated interest among the Adventure Time fandom's dirty-minded sect.
How Are The NSFW 'Adventure Time' GIFs Spreading On Twitter?
The Marceline GIF hit the timeline on November 10th, 2025, when Twitter user @casketmourn posted the thing with the caption, "I put body lotion in my Amazon cart." The GIF caption post used the Marceline "burst" animation to represent decadence or indulgence.
In the following weeks, the GIF has spread like wildfire. "I brace myself for impact every time this ends up on my timeline now," wrote user @p3pbutt in a viral quote-tweet.
The post they captioned didn't even attach the NSFW version. Instead, the user shared the SFW version, which startled @p3pbutt before letting them off easy.
The Princess Bubblegum GIFs are spreading similarly. Users are either posting them as GIF caption memes or they're posting the normal versions of the GIFs to humorously play with people's expectations.
"These GIFs are spreading like coke in the '80s," wrote user @cloudwing0 in a viral post from yesterday, emphasizing the viral spread of the animations in question.
