Can’t crack the Neptunite in SL300? Here’s how to bust it open and beat Battle Challenge 6 (Banana 58) in Donkey Kong Bananza’s Canyon Layer.
Neptunite: The Rock That Won’t Budge
If you’ve made it to Canyon Layer SL300 in Donkey Kong Bananza, you’re probably feeling like a jungle boss—until you bump into Neptunite, the stone equivalent of “You shall not pass.” It’s guarding the entrance to a challenge room near the Click-Clack Smokestack Roof checkpoint.
Smashing it? Not gonna happen. Tossing boulders? Useless. Transforming into Kong Bananza and flexing? Still nope.
But hey, we’ve got the solution—and no, it’s not brute force.
How to Break Neptunite in SL300
This one’s less about muscle, more about money.
Just to the left of the Neptunite-covered entrance, you’ll find a Constructone worker rocking a safety hat. Talk to him and he’ll explain that the ruins are sealed tight.
Here’s the trick:
- Pay him 600 Gold
- Watch him blow that Neptunite sky high like it’s nothing
Yeah, that’s literally it. DK just became the bankroll for demolition services.
Pro Tip: If you’re low on gold, smash nearby crates, dig around, or backtrack through earlier layers. 600 gold is chump change once you’ve been smashing and grabbing everything in sight.
Banana 58 – Knotted Thorn Knockout Challenge
Once Neptunite’s gone and the entrance opens, you’ll drop into Battle Challenge 6, officially tied to Banana 58.
Inside, you’re up against two Stompoids—those chunky, spiky boys that love to body slam.
How to Win:
- Don’t punch them. You’ll get spiked.
- Instead, pick up nearby rocks and chuck them like the jungle artillery you are.
- Keep moving and bait their slams so you’ve got time to aim.
- There’s a timer, so don’t dilly-dally. If you mess up, no worries—you can retry as many times as needed.
Reward:
One glorious Banandium Gem, ready to power up your skills and take DK from “banana bruiser” to “jungle juggernaut.”
Final Thoughts from the Smokestack
Neptunite’s a fake-out. It looks like a puzzle, but it’s really a tollbooth. Toss some gold, get it blown up, and you’re in.
And once you’re inside, it’s just good ol’ fashioned rock-throwing combat—timed, chaotic, and kind of satisfying when you finally take those spiky boys down.
So yeah, Banana 58? Totally worth the gold. Get in, get your gem, and keep climbing toward that skill tree greatness.
