The Spinning Laser Zone in Donkey Kong Bananza is one of the most demanding challenge courses in the Canyon Layer, featuring rotating laser traps and hidden collectibles. If you’re struggling to find all 3 Banandium Gems in Challenge Course 4 (SL301), this guide explains how to retrieve each one safely—especially the second, which is well hidden.
Spinning Laser Zone Location
- Area: Banandium Refinery Terrace, Canyon Layer
- Challenge Course ID: SL301 (Canyon Layer Challenge Course 4)
- How to Reach:
After defeating Grumpy Kong and entering the Banandium Refinery (Sublayer 301), follow the path from the Staff Dormitories. The course is embedded in a wall just before the minecart that leads to the Mad Mixer encounter.
Steps to reach the challenge quickly:
- Use the minecart to Longneck Plateau.
- From the village, follow the path up the slope to the Banandium Refinery.
- Once inside, advance through the ruins to the dormitory area and look for the course mounted on the stone wall near the second minecart.
Preparation Tip: Activate the Getaway near the Staff Dorms for extra hearts and a safe respawn point. This is helpful, as you’ll face layered hazards including lasers, buried collectibles, and vertical terrain shifts.
Banandium Gem #1 – Past the First Laser Grid
This is the most accessible gem in the course.
- Location: Immediately after the first two spinning lasers.
- Steps:
- Perform a Hand Slap (R Button) on cracked terrain with a Hand Slap marker to raise a stone wall.
- Wait for the laser to rotate past, then proceed.
- The Banandium Gem is visible and located just beyond the raised wall.
Tip: Use terrain strategically. The environment is soft dirt, allowing safe manipulation and easier avoidance of hazards.
Banandium Gem #2 – Hidden in the Final Laser Section
This gem is buried and easy to miss.
- Location: Within the third laser chamber, near the course exit.
- Steps:
- Activate Scan Mode (hold R) to reveal a buried gem near a concrete slab and Hand Slap panel.
- Use a Hand Slap to mark and expose the weak spot.
- Dig directly down into the dirt. Avoid the rotating laser by waiting for a safe gap.
- Break open the gem once unearthed.
Note: This area has slower rotating lasers, giving you more time to dig and avoid damage.
Banandium Gem #3 – Final Arena
- Location: At the end of the obstacle course, just before the exit platform.
- Steps:
- Use a Hand Slap to raise a wall to block the final rotating laser.
- Dig beneath the terrain to safely avoid the laser path.
- Advance to the final section and raise the exit platform with another Hand Slap.
- Collect the final Banandium Gem.
Spinning lasers at the end follow complex angles—prioritize movement over speed.
Terrain Mechanics Overview
The Spinning Laser Zone isn’t just about avoiding hazards—it’s about mastering the environment itself. Terrain manipulation is critical to both survival and progression. Here’s how each element works in this course:
Soft Dirt Terrain – Digging for Safety and Secrets
Much of the course is built on loose soil, which DK can dig through using standard ground actions. This feature is used in multiple ways:
- Tunneling beneath lasers to avoid direct exposure.
- Uncovering hidden Banandium Gems, especially in the final chamber.
- Creating custom safe paths through wide-open hazard zones.
Tip: Always wait for a laser to pass before starting to dig. This gives you enough time to reach your destination before the beam rotates back.
Hand Slap Panels – Raising Terrain and Creating Barriers
Certain panels on the ground are marked for Hand Slap activation. Pressing R here will raise platforms or vertical walls. These features are essential for:
- Blocking rotating lasers and creating temporary safety.
- Elevating DK to platforms, especially at the course’s end.
Example: You’ll need to use a Hand Slap to raise a wall that protects you from lasers when collecting the first gem, and again to raise a pillar that grants access to the final gem.

Tip: Look carefully for these markers, especially near laser paths—they often provide the only safe route forward.
Laser Movement Patterns – Predictable and Exploitable
The rotating lasers follow fixed, consistent paths, either in full circles or sweeping arcs. Once you observe their motion:
- Memorize the rotation speed and direction.
- Plan movement or digging actions accordingly.
- Wait for natural openings instead of forcing progress.
Tip: Study one full rotation before taking action. Most errors happen from acting too soon.
| Mechanic | Function | Application in Spinning Laser Zone |
|---|---|---|
| Soft Dirt | Allows digging under lasers and surfaces | Used to reach hidden Gem #2 and bypass hazards |
| Hand Slap Panel | Raises protective walls or new platforms | Needed for Gem #1 shield and Gem #3 exit |
| Laser Rotation | Fixed movement pattern; plan accordingly | Allows safe timing for digging and crossing |
