What am I doing here?Forbidden Layer is a floating-island route with concrete platforms, gold-paid traversal gates, and prismatic puzzles. Track paid access points separately from form gates. All five Bananza forms are in play — use each where the island route specifically supports it.
What controls matter here?Move

What Bananza power matters here?All five Bananza forms (Kong, Zebra, Ostrich, Elephant, Snake) are available.
Snake Bananza is useful for vertical repositioning between floating islands.
Ostrich Bananza is useful for gliding between platforms.
Zebra Bananza is useful for speed-crossing routes.
No new Bananza form is confirmed as unlocking in Forbidden Layer.

Floating-island route and paid traversal

  1. Tasks: Identify the main floating-island path before paying for optional access.; Record Securitone-style paid routes and gold costs separately from form-gate routes.; Group visible Banandium Gems by nearest island, prismatic object, challenge entrance, or paid route.
  2. Bananza power or form: Forbidden cleanup uses late-game movement tools across floating concrete islands. Label the form requirement only when the route clearly confirms it. Late-game forms can solve similar problems in different ways, so note the route type, not just the form.
  3. Boss or major encounter: None verified for this sublayer. No boss is confirmed for the main Forbidden Layer route. Gold management is as important as movement here. Record paid access points so a return visit does not require re-clearing the whole layer.
  4. Collectibles: Banandium Gems tied to floating islands, prismatic puzzles, combat routes, and paid access zones.; Post-story or character-specific rewards should go in a return list.
  5. Cleanup before leaving: Keep any post-story or character-specific rewards in a separate return list.; Confirm Planet Core transition is the correct forward path — DK Island remains DLC or postgame, not Layer 17.
  6. Unlocks next: Planet Core (Layer 17) — the final numbered base layer in Donkey Kong Bananza.

Sublayer 1500-cleanup

Forbidden cleanup and Planet Core prep

  1. Tasks: Complete any Forbidden Layer collectibles skipped due to gold cost or form requirements.; Separate Forbidden notes from Planet Core prep before leaving.; Return after Planet Core if post-story rewards are gated behind the story completion state.
  2. Bananza power or form: Use recorded island-route notes and form types to target specific cleanup items without re-clearing the layer.
  3. Boss or major encounter: None verified for this sublayer. No boss is associated with the Forbidden cleanup return. This is a targeted cleanup pass. Gold management is the primary constraint.
  4. Collectibles: Skipped Forbidden Banandium Gems grouped by paid-gate, prismatic, combat, or form-gate type.; Post-story rewards that require Planet Core completion.
  5. Cleanup before leaving: Keep Forbidden cleanup notes separate from Planet Core progression.; DK Island belongs outside the numbered base layer rail — do not fold it into this layer's cleanup.
  6. Unlocks next: Planet Core (Layer 17), the last base-game layer.

Route Walkthrough

4 Route Steps
01
Arrival

Use Sublayer 1500 as the Forbidden Ledger

  1. Forbidden Layer is documented as a single-sublayer route, so keep all notes under Sublayer 1500 with island and activity labels.
  2. Start by identifying the main floating-island path before paying for optional access or chasing distant rewards.
  3. Record visible Banandium Gems by nearby island, prismatic object, challenge entrance, or paid route.
02
Economy

Track Gold-Paid Traversal Before Spending

  1. Source guides document Securitone-style paid routes and gold costs as part of Forbidden cleanup.
  2. Write down paid access points separately from transformation routes so a low-gold return plan is possible.
  3. If a paid route has an alternate movement solution, wait for the collectible source record before publishing exact directions.
03
Movement

Separate Snake, Ostrich, Zebra, and Prismatic Checks

  1. Forbidden cleanup uses late-game movement tools across floating concrete islands.
  2. Group skipped rewards by form requirement, prismatic puzzle, combat route, or precision movement route.
  3. Do not publish exact floating-island lines until the route is verified in the collectible record.
04
Exit

Prepare for Planet Core Without Renumbering DLC

  1. Before leaving, confirm Forbidden cleanup notes are separated from Planet Core prep.
  2. Keep any post-story or character-specific rewards in the return list.
  3. Continue to Planet Core as Layer 17; DK Island remains DLC or postgame content, not a numbered base layer.
