The Power Source in Fisch is a shop purchase costing 55 Glorp Bux, and you need it as a component for the D.R.E.D-7 Rod. Head to the Glorp Shop in Roslit Bay, behind the Nurse Shark bestiary pool, once you own the Blade of Glorp. Earning the currency means exchanging fish with the Gleebus Mutation. This Roblox guide covers the requirements, the fishing and trading routes, the exact shop coordinates, and what to do when the rotating stock gets in your way.
What do you need before buying a Power Source?
Start with the Blade of Glorp ownership requirement. Even if you already have enough Glorp Bux, you cannot open the Glorp Shop without owning this rod.
Your purchase checklist is short:
- Own the Blade of Glorp to access the shop.
- Collect Gleebus Mutation fish to exchange for Glorp Bux.
- Save 55 Glorp Bux for the Power Source.
Trading can help you obtain the required fish, but it does not replace the Blade of Glorp ownership requirement. Sort out shop access before spending time gathering fish for the exchange.

Equip Blade of Glorp first
If you still need help with fishing, rod progression, or island navigation, use the Fisch beginner's guide before tackling this purchase.
How do you earn 55 Glorp Bux?
Sophisticated Glorp exchanges fish carrying the Gleebus Mutation for Glorp Bux. The mutation is the requirement here: any fish with Gleebus can be used for the exchange.
Catch Gleebus fish with the Blade of Glorp
Equip the Blade of Glorp and fish with it. The rod has a 36% chance to apply the Gleebus Mutation, making it the fishing route for collecting exchangeable catches.
Keep the Gleebus fish for Sophisticated Glorp, then exchange them and work toward a balance of 55 Glorp Bux. That is the amount needed for the Power Source itself.
Obtain Gleebus fish through trading
Trading is the other route to fish with the Gleebus Mutation. Once you have them, exchange those fish with Sophisticated Glorp just as you would your own Gleebus catches. You still need to own the Blade of Glorp to access the shop afterward.

Trade Gleebus fish for Bux
Keep separate mutation goals separate. The Noxious mutation guide covers another target, while this Glorp Bux exchange specifically requires Gleebus fish.
Where is the Glorp Shop in Fisch?
Travel to Roslit Bay and locate the Nurse Shark bestiary pool. The Glorp Shop is behind that pool, where you can speak with Sophisticated Glorp.
Use these GPS coordinates to locate the shop:
- X: -1790.6
- Y: 155.0
- Z: 509.2
The pool gives you the nearby landmark, while the coordinates identify the shop's position. Once you reach Sophisticated Glorp, interact with the NPC to access the shop dialogue.

Locate the Roslit Bay shop
How do you purchase the Power Source?
With the Blade of Glorp owned and at least 55 Glorp Bux saved, the purchase is straightforward. Speak with Sophisticated Glorp and follow these steps:
- Choose Show me your shop in the dialogue.
- Find Power Source in the shop stock.
- Select it and pay 55 Glorp Bux.
- The Power Source is added to your inventory.
This gets you the component needed for the D.R.E.D-7 Rod. The Power Source itself comes from this purchase, so focus your fishing on earning Glorp Bux through Gleebus fish.
What else can you spend Glorp Bux on?
The Glorp Shop also sells other items, including cosmetics and totems. If your immediate goal is the D.R.E.D-7 Rod component, keep 55 Glorp Bux as a reserved balance until you buy the Power Source.
| Item | Glorp Bux required | Compared with the Power Source |
|---|---|---|
| Power Source | 55 | Your component target |
| Disturbance Catalyst | 215 | Costs more |
| Rainbow Totem | 665 | Costs more |
| Eclipse Totem | 800 | Costs more |
| Alien Nico Skin | 3,000 | Costs more |
Other rotating items include the Blade of Glorp Skin, Glorp Bobber, Glorp Profile Banner, and :3 Title. The shop rotates every 24 hours, so its stock can differ between visits.
Why can't you get the Power Source yet?
The most useful check depends on where you are blocked. Shop access, currency, and rotating stock are separate parts of this purchase.
| Problem | What to check | Next action |
|---|---|---|
| The Glorp Shop will not open | Blade of Glorp ownership | Obtain the rod before trying again |
| You need more Glorp Bux | Fish mutation | Exchange Gleebus Mutation fish with Sophisticated Glorp |
| Your balance is below 55 | Power Source budget | Continue exchanging Gleebus fish |
| Power Source is missing | Current shop rotation | Check again after the 24-hour rotation |
For the shortest route through this task, handle the Blade of Glorp requirement first, gather Gleebus fish, and save the full 55 Glorp Bux before shopping. Once the Power Source is in your inventory, choose another rod project with the Record Breaker Rod unlock guide.
