Video: Bob-Omb Battlefield is located, two switch courses are cleared, and Bowser in the Dark World refuses to stay where it belongs.


A Quick Investigation

With Rainbow Ride finally behind me, I decided it was time to start figuring out what the castle was actually hiding.

My first stop was the area that would normally contain the Secret Aquarium.

Instead, the randomizer had placed Bob-Omb Battlefield there.

I had a quick look around, but it didn’t take long to realise there wasn’t much point staying.

A lot of the stars appeared to require the Wing Cap, and since I don’t actually have access to it yet, I decided there was little point forcing the issue.

I’d rather finish a course in one visit than collect a couple of stars and immediately leave again.

With that in mind, I backed out and continued exploring.

The Vanish Cap Switch

Next, I paid a visit to the painting that would normally lead to Jolly Roger Bay.

Inside was the Vanish Cap Switch course.

That was good news.

The switch courses are useful because once they’re done, they’re done.

No wondering whether I missed a star.

No revisiting them later.

Just one objective and a clear result.

The randomizer was fairly kind here. I spawned at the top of the slide, which allowed me to collect red coins as I made my way down. The switch itself was also much closer than usual.

Getting the star turned out to be the difficult part.

The star had spawned close to my starting position, meaning I effectively had to complete part of the course backwards.

That sounds simple enough until muscle memory starts fighting back.

I’m used to travelling through this course in one direction. Suddenly doing the opposite felt surprisingly awkward.

Eventually I reached the star and collected it, putting the first switch course firmly in the completed column.

The Metal Cap Switch

The next stop was the Cool, Cool Mountain painting.

Inside was the Metal Cap Switch course.

At that point I realised I was about to clear two of the three cap courses in a single entry.

Naturally, this made me hopeful that the Wing Cap Switch might be waiting nearby somewhere.

Unfortunately, I remembered my original randomizer run.

The Wing Cap hadn’t appeared until Hazy Maze Cave during that seed, so there was no guarantee it would show up any time soon.

The Metal Cap course itself was fairly straightforward.

I’ve done the red coin route enough times over the years that most of it feels automatic now.

I still needed to make proper use of the Metal Cap in a few places, but nothing caused any major problems.

Before long, the star was collected and a second switch course had been crossed off the list.

The Garden Surprise

My plan for this randomizer has always been to work my way down through the castle before heading upwards.

Technically I could have visited the trapdoor that normally leads to Bowser in the Dark World.

Instead, I wanted to investigate the courtyard first.

The Boos had been waiting there for several entries now, and I wanted to know what they were hiding.

The answer turned out to be Bowser in the Dark World.

Of course it was.

Apparently Bowser’s first stage has decided it would rather spend this seed pretending to be Big Boo’s Haunt.

At least that answers one question.

Unfortunately, it also creates another.

It looks like I’m not getting out of going there after all.

End Of Entry Status

Two switch courses have been completed.

Bob-Omb Battlefield has been located.

Bowser in the Dark World has revealed its new hiding place.

The Wing Cap remains missing.

And the castle continues to make its own decisions regarding sensible level placement.

  • Stars Collected: 16 / 119

With Dice-Fortress finally behind me, the obvious next step would have been to head back to the Tower of the East and continue there. The problem is that the next course in that area needs the Vanish Cap, and I’d rather avoid unnecessary backtracking if I can help it. So instead, I stayed where I was, unlocked another star door, and made use of what was already available. Inside was the pink Bob-Omb, who opened a cannon I’ll be coming back to later, but for now there were two courses to choose from. The first of those was Stalagmite Cave.

The first star, Downwards, doesn’t leave much room for interpretation. A sign at the top makes two things clear before you even start: once you go down, there’s no going back, and there are no coins waiting at the bottom. With that in mind, I took the drop. The plan was to land cleanly in the water. The reality was the same as it had been during practice — not quite. Close enough to recover, though, and once I was in the water the star was straightforward to collect.

Sweating Tunnel came next, and getting there meant heading back up through the level. Wall kicks, careful movement, and just enough awareness to avoid losing progress to something minor. The bat up there isn’t dangerous, but it’s the kind of thing that can break your rhythm at the worst possible moment. I passed the Thwomps and the Chuckya platforms on the way, both of which I knew I’d be dealing with later, and kept moving toward the lava path. A series of descending platforms over lava isn’t the place to hesitate, so I stuck with long jumps and kept the momentum going. It worked this time, though I know from practice that it doesn’t always.

The red coins and 100-coin star followed, and this part of the course felt more controlled. There’s space to move, room to plan, and not much pressure unless you create it yourself. I made a point of leaving the final coins close to where the red coin star would appear, just to avoid any unnecessary movement at the end. It paid off. No mistakes, no wasted time, just two more stars added cleanly.

Hot Obstacle Course was next, though the name doesn’t quite match what it asks of you. This is where the Thwomps come into play properly. Three of them, spaced just far enough apart to force you to commit to each jump. It’s more about timing than anything else. Get that right, and the star is waiting at the end.

Chuckya’s Challenge lived up to its name a bit more. Platform to platform, each one guarded, each one needing just enough precision to avoid being grabbed and thrown back. I decided to push back a little on one of them, which didn’t go to plan the first time, but the second attempt was cleaner. A few long jumps later, and that was another star secured.

That left the reason I came here in the first place: Cap-Combination. This one needs both the Metal Cap and the Wing Cap active at the same time, which meant heading back down the slide and setting things up properly. I grabbed the Metal Cap first, then the Wing Cap, partly out of habit and partly because I trust the Wing Cap timer slightly more, even if I don’t know exactly how much difference it makes.

From there, it was a matter of flying over to the underwater switch, activating it, and dealing with the timed path that follows. It’s longer than it looks, and the slope works against you just enough to make every second count. Walking is possible, but I found jumping kept the pace up better. Even then, it took a few attempts to get everything lined up properly. Timing, positioning, momentum — all of it had to come together. Eventually it did, and once it did, the rest of the path felt manageable.

One final flight to the star, and Cap-Combination was done.

There’s still another course in this area to deal with, but that can wait for the next entry. For now, Stalagmite Cave is cleared, and more importantly, one of the more awkward stars in this section is out of the way.

Video: Azure Abyss red coins, 100-coin star, Metal Cap puzzle, and Wall of Failure attempts (no commentary)


Back to Azure Abyss, and straight into what I knew was going to be a longer task — the red coins, or Red Treasure Hunt as this one is called, along with the 100-coin star on top of it. The layout of this course makes it awkward to rush anything. It’s deeper than it first looks, and the last thing I wanted was to be scrambling for air because I got careless. So I took it slower, moving between the land sections and the underwater routes, trying to keep things controlled rather than efficient.

Somewhere along the way I realised my swimming had improved without me really noticing. I’m not about to claim anything close to speedrunner level, but there was a rhythm to it that I don’t remember having before. Funny how that happens just by playing more. It made the coin collection smoother, even if it didn’t make it any shorter.

The red coin star itself sits safely above the water, which helps, but by the time I had all eight coins I was still short on the total. That’s when it turned into a bit of a hunt. I hit 97 coins and started running out of places to check. I didn’t want to spend more time swimming if I could avoid it, so I went after one of the flying enemies, hoping it would drop what I needed. It dropped two coins. 99. Close enough to be frustrating.

I eventually tracked down the final coin, though it took longer than it should have, and with that both the red coin star and the 100-coin star were done. Not difficult, just drawn out enough to make every mistake feel like wasted time.

Next was Heavy Metal Required, and the name doesn’t leave much to guess. I needed the Metal Cap. I’ve seen this done without it, but I’m not interested in making things harder than they need to be, so I stuck with the intended route. With the cap active, I could sink properly underwater and push the purple switch, which brought out the timed blocks.

Everything felt fine at first. The jumps were clean, the timing felt right, and then right at the end I walked straight off the final block. No complicated mistake, no bad angle, just walked off. The second attempt went the way the first one should have, and the star was mine without any further issues.

That left one final star in the course: Wall of Failure. The name fits. I knew exactly what I needed to do — get onto the platform, long jump, grab the ledge — and in theory it’s simpler than the alternative route. In practice, it took far longer than it should have. I lost count of the attempts. Too much distance, not enough distance, missing the ledge entirely, every variation you can think of showed up at least once.

When it finally worked, it wasn’t clean or dramatic, it just… worked. Mario grabbed the ledge, pulled himself up, and the star was there. That was Azure Abyss done.

Even with the course complete, I’m still two stars short of opening the next star door in this area. That means next time I’ll be heading through the double doors instead. I already have the key from Bowser, so it’s time to open up more of the castle and see what else this hack has waiting.
