Donkey Kong Bananza Guide#
Donkey Kong Bananza is a 3D platformer built by Nintendo exclusively for Switch 2, launching worldwide on July 17, 2025 at $69.99 (HK$449 digital / HK$499 physical on the Hong Kong eShop, with the physical edition a full cartridge rather than a key card). It comes from Nintendo EPD’s Production Group No. 8 — the team behind Super Mario Odyssey — working with 1-Up Studio, produced by Kenta Motokura and directed by Kazuya Takahashi, with Shigeru Miyamoto personally weighing in on the game feel. It is the first 3D Donkey Kong platformer in 26 years, since Donkey Kong 64 (1999), and the first brand-new entry in the series since Tropical Freeze (2014).
The whole game rests on one idea: punch your way through the world. Terrain is no longer scenery but raw material — smash through it, hollow it out, shatter it vertically, tear chunks free and hurl them as weapons. Destruction-as-exploration runs through all 17 layers: Banandium gems hide behind walls, secret passages run underfoot, and puzzle answers are written into the rock at your feet. This 22-page guide hub takes that destruction-driven collect-a-thon apart piece by piece — layer structure, the destruction toolkit, five transformations, gem and fossil tracking, boss fights, and everything waiting after the credits.

Why It’s Worth Firing Up Switch 2 For#
Destruction is the freest ability in platforming. Most games in the genre funnel you along designed paths; Bananza does the opposite, making almost every wall and floor smashable. Ram a wall to open a tunnel, pound straight down to punch through multiple underground strata, or rip a slab of terrain clean off and throw it as ammunition. Nintendo turned this voxel-style destruction into a language of exploration — spot a suspicious rock face and smash it, see a dent and drop in — and that instinct carries you from Ingot Isle all the way down to the Planet Core.
Collectibles carry real weight here. All 777 Banandium gems, golden banana-shaped treasures buried behind walls and under the ground, are the source of skill points: every five gems trade for one point, with 749 needed to fill out the standard skills and transformation upgrades and another 125 held back for post-game content. The 696 fossils work as a separate fashion currency with strict layer locks — a layer’s fossils only buy that layer’s outfits. Collection stops being a percentage on a screen and becomes hard currency for power.
Five transformations, five different games. As the story unfolds, DK unlocks Kong, Zebra, Ostrich, Elephant, and Snake forms — and the layers are built to force form-switching puzzles, with the Freezer Layer’s collapses demanding Zebra speed and the Radiance Layer’s darkness calling for the Snake’s gaze.
| Form | Signature Playstyle |
|---|---|
| Kong | Smashes through hard terrain with raw power |
| Zebra | High-speed dashes; built for outrunning collapses |
| Ostrich | Glides through the air and dive-strikes |
| Elephant | Swallows soil and spits it back as stone |
| Snake | Double jump, bullet-time focus, and a gaze that reads the dark |
Key Numbers at a Glance#
Five anchor numbers to keep in mind before opening any guide page:
| Number | What It Means |
|---|---|
| 17 | Total layers, stacked in a vertical structure numbered SL1 through SL1609 |
| 777 | Total Banandium gems; every 5 gems convert to 1 skill point |
| 696 | Total fossils — the layer-locked currency for Style Shops |
| 108 | Challenge Ruins, the organized backbone of gem income |
| 5 | Transformations: Kong / Zebra / Ostrich / Elephant / Snake |
For pacing: budget 10-12 hours for the main story and 50-60 hours for full completion — the completion-planning guide splits the long hunt into three stages.
Suggested Reading Routes#
New to the game: start with the overview to get your bearings on Ingot Isle and the Underground World, then follow the beginner’s guide for early skill priorities (health → Hand Slap sonar → beeline for the Zebra form), using the layers overview for the big picture. When you reach the branch at The Divide, the conclusion is simple: both routes have to be cleared eventually, but taking the Freezer Layer first makes for a smoother run.
Completionists: three pages do the heavy lifting. The Banandium gem guide lists per-layer quotas and sources for all 777; the fossils and outfits guide explains the layer-lock rules so you don’t waste a trip; and the completion-planning page is the schedule for the 50-60 hour long haul. The good news: nothing is permanently missable, so everything can be cleaned up after the credits.
Story seekers: the Pauline and VoidCo pages piece together the full narrative — 13-year-old Pauline, the Odd Rock, the singing that triggers transformations, and the race to the Planet Core — while the series-history page tackles the tastiest speculation in the community: Pauline’s possible ties to Super Mario Odyssey (media speculation, not confirmed by Nintendo). After the credits, the post-game page hides an ending worth chasing.
Stuck on something: head straight to the FAQ page and work through the progression, transformation, collection, combat, and environment groups; the glossary covers Banandium gems, Bananergy, Getaways, and the Warp Gong for quick lookups.
FAQ#
Is Donkey Kong Bananza an open-world game?#
No. Despite its scale, it is a sandbox-style 3D platformer built on 17 discrete layers, not an open world.
How long does it take to beat?#
Roughly 10-12 hours for the main story and 50-60 hours for full completion.
Is there DLC?#
Yes. The paid expansion DK Island & Emerald Rush launched on September 12, 2025.
Is the physical edition a full cartridge?#
Yes — the physical release is a complete cartridge, not a Switch 2 key card.
Does the game support co-op?#
Yes. A second player can join in as Pauline with sound-wave-based gameplay, with GameShare and motion-control support.
Can you permanently miss collectibles?#
No. Every Banandium gem and fossil can still be collected after you finish the story.
How many collectibles are there in total?#
777 Banandium gems, 696 fossils, and 108 Challenge Ruins, on top of five transformations to unlock.
Is it connected to Super Mario Odyssey?#
It is the first 3D Donkey Kong platformer since Donkey Kong 64 (1999) and the first original series entry since Tropical Freeze (2014), built by the Super Mario Odyssey team. The 13-year-old Pauline has fueled media speculation that Bananza is a prequel to Odyssey, but Nintendo has not confirmed any link.
Editor’s Verdict#
This is not a series comeback running on nostalgia; it is a systematic rebuild that treats destruction as a core language. Terrain shatters, collectibles gain value, transformations rewrite the gameplay, and Switch 2 keeps this voxel-level destruction running smoothly at 1080p/60fps. An IGN 10/10 and a 91 on Metacritic carry real weight here — play the first hour and you will feel it: the joy of smashing a wall open with one punch is something the platforming genre has been waiting years for.
