Forbidden Planet has announced a significant expansion to its exclusive merchandise lineup for 2026, returning to the Land of Ooo with a new collection of Adventure Time apparel and accessories.
The specialist retailer, known for its exclusives on pop culture franchises, revealed the range this morning. The collection focuses heavily on fan-favourite characters, with the living video game console BMO taking centre stage alongside series protagonists Finn and Jake.
Headlining the drop is a knitted BMO jumper, priced at £49.99, which recreates the character’s teal face and button interface. For those looking for lighter wear, the range includes several t-shirts priced at £19.99. Designs include a “Return to Ooo” motif and an “Oh My Glob!” shirt featuring Lumpy Space Princess, capturing one of the show’s most enduring catchphrases.
The collection also leans into the “Bubbline” pairing, the relationship between Marceline the Vampire Queen and Princess Bubblegum, which was confirmed in the series finale and further explored in the Distant Lands specials. A dual enamel pin badge featuring both characters is priced at £7.99.


Other accessories in the 2026 wave include:
- Enamel Pin Badges (£7.99): Individual designs for Jake, Finn, BMO, and Lumpy Space Princess.
- Keychains (£9.99): Featuring BMO’s face.
- Beanies (£19.99): A BMO face design to match the jumper.
- Homeware: “Return to Ooo” tote bags (£9.99), art prints (£9.99), and mugs (£7.99).
While the original Adventure Time series concluded its ten-season run in 2018, the IP has remained a cornerstone of geek culture, bolstered by the Distant Lands specials on HBO Max and the recent spin-off Fionna and Cake. Forbidden Planet’s decision to launch a broad exclusive range in 2026 suggests they see no decline in the demand for Ooo-related merchandise.
