So you’ve been running around the islands in Fisch on Roblox and realized that your character moves at the speed of a tired snail. It’s frustrating. You see other players zooming past you like they’ve got rockets strapped to their ankles, and you’re stuck wondering what secret sauce they’ve found. Well, the secret isn’t a sauce—it’s a guy named Dr. Crookspine.
Most people call him Dr. Crook spine or some variation because, let’s be honest, his name is a mouthful. But if you want to fix your walking speed, you have to track him down. He’s the only NPC who can give you the Glimmersuit Boots, which literally double your walking speed.
Getting them isn't exactly a walk in the park, though. It’s a grind.
Finding the Oil Rig (Without Getting Lost)
First things first: you can’t find Dr. Crookspine if you don’t know where the Oil Rig is. Honestly, the ocean in this game can feel massive when you’re just staring at blue waves, but the rig is pretty distinct once you know the landmarks.
Basically, you want to head over to Roslit Bay. Once you’re there, look toward the horizon. You’re looking for a massive, industrial-looking structure—the Oil Rig. It’s tucked away between Roslit and Sunstone Island. If you’re a fan of coordinates, aim for roughly X: -1785, Y: 130, Z: -485.

When you pull your boat up to the rig, don't just stand on the deck. Look for a Shipwright NPC standing near a rope or a pole. You’ve gotta climb that. Dr. Crookspine isn't hanging out with the grease monkeys on the lower level; he’s got a laboratory setup on the upper floor. Climb up, enter the room on the right, and you’ll see him—a scientist NPC who looks like he hasn't slept in three weeks.
The Dr. Crookspine Invention Quest
Talk to him. He’s going to ramble about his latest invention, the Glimmersuit Boots. He doesn’t just hand them over, though. He needs parts. Specifically, three "secret" items that you have to catch while fishing. This is where the real work starts because these items have a Secret rarity.
You’re going to need a lot of patience, or better yet, a lot of luck buffs.
What You Need to Catch
I’ve seen people spend hours trying to get these in the wrong spots. Don't be that person. Each item is tied to a specific location:

- The Boots: These are the "base" for his invention. You can catch these anywhere in the Ocean. Just cast your line into the deep blue and hope for the best.
- Rocket Fuel: This one is specific. You have to go to Mushgrove Swamp. It makes sense if you think about it—swamp gas, chemicals, whatever.
- Speed Core: Head over to Sunstone Island. This is usually the item that trips people up the most because the drop rate feels incredibly low.
How to Actually Catch "Secret" Rarity Items
If you just go out there with a basic rod and zero buffs, you’re going to be fishing until 2027. "Secret" rarity is no joke.
Kinda common sense, but you should be using Merlin’s Luck or Aurora Totems if you have them. If you’re playing during an event where luck is boosted, that’s the time to strike. Some players swear by using the reinforced rod or better just to handle the potential tension, but honestly, it’s more about the luck stat than the rod’s strength for these specific quest items.
Once you have all three—the Boots, the Rocket Fuel, and the Speed Core—head back to the Oil Rig. Hand them over to Dr. Crookspine, and he’ll give you the Glimmersuit Boots.
Why the Glimmersuit Boots Are a Game Changer
Let’s talk about why you’re even doing this. The Glimmersuit Boots provide a 2x walking speed multiplier.

In a game where you’re constantly running between shops, docks, and secret fishing holes, doubling your speed isn't just a "nice to have." It’s a necessity for high-level play. It makes the grind for rare fish much less tedious because you aren't spending half your session just walking from point A to point B.
What Most People Get Wrong
The biggest mistake? Thinking Dr. Crookspine is a one-and-done NPC. While the boots are his main draw, his location on the Oil Rig makes him a central figure for anyone trying to optimize their setup.
Also, don't confuse him with other NPCs who might give gear. He is specifically the "tech" guy for the Glimmersuit. If you lose your boots or something glitches (it’s Roblox, it happens), he’s the guy you need to remember.
Another tip: don't try to fish for the Speed Core at Roslit just because it's near the rig. Go to Sunstone. The game code is picky about where these quest items drop.
Actionable Steps to Get Your Speed Boost
- Stock up on Luck: Buy Merlin’s Luck or wait for an Aurora weather event before you start.
- Hit the Swamp First: Mushgrove Swamp is a bit out of the way, so grab the Rocket Fuel first to get the most annoying part over with.
- Farm the Ocean: While traveling between islands, keep your rod out. You might snag the Boots naturally without even trying.
- Finish at Sunstone: Get that Speed Core, then it’s a short boat ride back to the Oil Rig.
- Equip and Zoom: Once you get the Glimmersuit Boots, make sure they are actually equipped in your inventory to see the speed boost.
Getting the Dr. Crookspine quest done is basically a rite of passage in Fisch. It’s the moment you stop being a "newbie" and start moving like a pro. Just be prepared for the grind—it’s called "fishing," not "catching," for a reason.
