Sublayer 1600

Planet Core entry and all-form prep

  1. Tasks: Confirm all five Bananza forms are available before pushing deep into Planet Core.; Make a return list for visible gems, challenge rooms, and transformation gates before advancing.; Keep story route progress separate from cleanup notes from the start.
  2. Bananza power or form: All five forms are active from the start of Planet Core. Use each form where the route clearly asks for it — Planet Core mixes form requirements across sublayers. Refill Bananergy at every opportunity.
  3. Boss or major encounter: None verified for this sublayer. Specific encounter details are kept spoiler-light on this page. Prepare all five forms before advancing and keep health and Bananergy topped up. Planet Core has confirmed late-game encounters. Keep precise encounter details out of the public route until a dedicated combat record is verified.
  4. Collectibles: Visible Banandium Gems near entry landmarks and accessible challenge rooms.; Note the form requirement for each skipped item rather than estimating exact positions.
  5. Cleanup before leaving: Do not force every collectible before the story route is secure.; Mark inaccessible items by sublayer number and form type for the return pass.
  6. Unlocks next: Sublayers 1601-1605 and the mid-Planet Core route.

Sublayer 1605

Mid and late Planet Core — challenge and cleanup

  1. Tasks: Work through Sublayers 1601-1605 as a combined challenge and cleanup block.; Keep thorn routes, shifty platforms, turf surfing, quiz checks, and chip-exchange notes in separate buckets.; Avoid documenting final encounter details publicly; keep the route focused on preparation and progress tracking.
  2. Bananza power or form: Planet Core cleanup uses all five forms across different sublayers. Refill Bananergy between major sections. If a challenge asks for a specific form and you are low, complete other nearby tasks first.
  3. Boss or major encounter: None verified for this sublayer. Specific encounter details are kept spoiler-light on this page. Prepare well; the final boss encounter is part of the Planet Core route. Long challenge sequences cost Bananergy. Do not enter a form-intensive challenge without refilling first.
  4. Collectibles: Banandium Gems across Sublayers 1601-1605 tied to various challenge and exploration types.; Planet Core has a smaller Banandium Gem set than some earlier cleanup layers.
  5. Cleanup before leaving: Separate postgame-only items from first-pass and first-return cleanup.; Confirm which sublayer each skipped gem belongs to before the return pass.
  6. Unlocks next: Sublayers 1606-1609, the final Planet Core push, and the walkthrough index for postgame cleanup.

Sublayer 1609

Final Planet Core push and postgame prep

  1. Tasks: Clear Sublayers 1606-1609 to complete the main Planet Core story route.; After the story is complete, use the walkthrough index to review cleanup notes across all 17 base layers.; Additional Ingot Isle cleanup becomes available after the story state changes — keep it as an Ingot Isle return note, not a new numbered layer.
  2. Bananza power or form: All five forms are needed for the final Planet Core push. Have Bananergy ready for any multi-form sequence the route requires.
  3. Boss or major encounter: None verified for this sublayer. The main Planet Core route ends the base game story. Specific final encounter details are kept spoiler-light on this page. After completing Planet Core, the Rowdy Race in Racing Layer (Layer 12) also unlocks. Return to the walkthrough index to prioritize postgame cleanup.
  4. Collectibles: Remaining Planet Core Banandium Gems in Sublayers 1606-1609.; Postgame Ingot Isle cleanup becomes available after the story is complete.
  5. Cleanup before leaving: DK Island is DLC or postgame content — it is not Layer 17 or a continuation of the numbered route.; Return to the walkthrough index to plan postgame cleanup across all 17 base layers.
  6. Unlocks next: Postgame — return to the walkthrough index for cleanup notes across all 17 base layers.

Route Walkthrough

4 Route Steps
01
Arrival

Confirm Planet Core as Layer 17

  1. Use Planet Core as Layer 17 in the base route and keep DK Island outside the numbered layer rail.
  2. Source guides document Planet Core across Sublayers 1600 through 1609 with a smaller late-game Banandium Gem set than some earlier cleanup layers.
  3. Before pushing deeper, make a return list for visible gems, challenge rooms, and transformation gates.
02
Preparation

Prepare Every Bananza Form

  1. Planet Core cleanup uses multiple Bananza forms, including Ostrich, Snake, Elephant, Kong, and Zebra utility.
  2. Refill Bananergy and health before long challenge routes, especially when the route asks for several form swaps in sequence.
  3. Record the form needed for each skipped reward rather than publishing exact hidden positions here.
03
Route Safety

Separate Story Progress From Cleanup

  1. Keep story route progress, combat checkpoints, thorn routes, shifty platforms, turf surfing, quiz checks, and chip exchange notes in separate buckets.
  2. Avoid documenting final encounter details on this page; keep the public route focused on preparation and cleanup tracking.
  3. If a reward is postgame-only, record that state clearly in the cleanup list.
04
Afterward

Return to Cleanup Without Renumbering DK Island

  1. After Planet Core, use the walkthrough index to review any skipped numbered layers.
  2. Source guides document additional Ingot Isle cleanup after the story state changes, so keep that as a return note for Ingot Isle, not a new numbered base layer.
  3. DK Island remains DLC or postgame coverage and is not Layer 17.
