Lost ‘Boob’ Levels from Super Monkey Ball Discovered After Ten Years

The Super Monkey Ball franchise has gone through some wild phases and crossovers, but few are as bizarre as the trio of levels inspired by a Japanese model’s chest in Super Monkey Ball Banana Splitz. Once thought to be lost to time, dedicated fans have now uncovered a way to bring these cheeky stages back into the game.

Surprisingly, these risqué levels aren’t the result of player-created content; they were official stages released in Japan as a limited-time bonus for early buyers of Banana Splitz. Each level revolves around model Yukie Kawamura, with her chest transformed into 3D obstacles. Originally, players could unlock these levels using a special code included with the game, but that code has since expired, making it a challenge for fans eager to revisit these quirky stages.

A video from a gaming channel detailed how these levels were rediscovered, showcasing full gameplay of each cheeky stage. It turns out the DLC was included in every copy of the game, regardless of region, and just needed to be unlocked. To access them, players must have a homebrew PS Vita, download a few files, and integrate them into the game using the Repatch plugin. The biggest hurdle for anyone wanting to experience these levels in 2026 is likely just finding a PS Vita.

Beyond the sheer absurdity of guiding a monkey over breast-themed ramps, the most amusing aspect of these levels is their surprising difficulty. The gaming channel describes them as both low quality and abstract, noting that players might find it easier to complete the three levels by exploiting glitches rather than following the intended path. It seems that tackling these cheeky challenges is reserved for Super Monkey Ball veterans only.
