Quick answer
The fastest way to get Glorp Bux in Fisch is to equip the Blade of Glorp rod, catch fish with the Gleebous mutation in Roslit Bay, and sell them to Sophisticated Glorp in his shop.
Glorp Bux is the odd currency standing between you and the Power Source, the item Dr. Anton needs for his D.R.E.D-7 rod quest at the Underground Music Venue. It will not show up in your wallet from normal fishing or from spending Robux, so most players get stuck not knowing which fish actually count.
This guide walks through the fastest loop for earning Glorp Bux in Roslit Bay, from unlocking the shop to selling your first Gleebous catch, so you can reach the 55 Glorp Bux you need and buy the Power Source.
Before you start
- Difficulty Moderate
- Time needed 45 minutes
- Works on Fisch on Roblox — Android, iPhone, and PC (same in-game steps)
What you'll need
- Fisch installed and updated to the current Roslit Bay/Alien content
- Character level 800–888 (sources disagree on the exact gate)
- Blade of Glorp rod obtained from Glorp's quest near the UFO crash site
- Dr. Anton's D.R.E.D-7 rod quest activated at the Underground Music Venue
Important
- Glorp Bux cannot be bought with Robux or real money, so skip any site or seller claiming otherwise.
Earn and Spend Glorp Bux at Sophisticated Glorp's Shop
This is the only known route to Glorp Bux, so treat it as the main grind rather than a shortcut.
Step 1: Level up and obtain the Blade of Glorp
Grind your character level first. Guides disagree on the exact cutoff: some put the shop’s unlock at level 888, others say level 800 combined with activating Dr. Anton’s D.R.E.D-7 rod quest at the Underground Music Venue.
Once you qualify, find Glorp near the UFO crash site at Roslit Bay and complete his quest to receive the Blade of Glorp rod. You need this rod both to catch the right mutation and, according to some players, to unlock the shop purchase option at all.
Tip: Activate the D.R.E.D-7 quest at the Underground Music Venue before you travel, since it may gate the Purchase button later.
Step 2: Travel to Roslit Bay and find Sophisticated Glorp
Open your in-game GPS or Fish Radar and set a waypoint for Roslit Bay. Glorp has moved into a proper shop there, and players now refer to him as
Step 3: Equip the Blade of Glorp and fish for Gleebous mutations
Switch to the Blade of Glorp rod before you start fishing in Roslit Bay. The rod raises your odds of rolling the Gleebous mutation to roughly 36 percent, which is far better than fishing with any other rod and hoping for a trade.
Keep casting until you land a fish with the Gleebous mutation. Only Gleebous-mutated fish can be exchanged for Glorp Bux, so ordinary catches from this spot are not wasted time but they will not pay out.

Tip: The mutation multiplies a fish's base value by 8x, so bigger or rarer Gleebous catches pay out more Glorp Bux.
Step 4: Talk to Sophisticated Glorp and sell your Gleebous fish
Interact with Sophisticated Glorp inside his shop. Choose the sell option for Gleebous fish, sometimes labeled

Step 5: Repeat until you reach 55 Glorp Bux
Keep fishing and selling Gleebous catches until your Glorp Bux balance hits 55, the price of the Power Source. Higher-rarity or heavier Gleebous fish close the gap faster, so prioritize those if you can tell the difference while reeling in.
Tip: Check Glorp's shop each day, since some players report the item list rotates and the Power Source is not always listed.
Step 6: Open the shop menu and purchase the Power Source
Talk to Sophisticated Glorp again and select the option to view his shop. Find the Power Source, choose Purchase, and confirm the exchange of 55 Glorp Bux for the item.
If the Purchase button stays greyed out, double check your level, your Blade of Glorp ownership, and whether you have activated the D.R.E.D-7 quest at the Underground Music Venue.

Pro tips
- Fish in short bursts specifically with the Blade of Glorp equipped rather than switching rods mid-session, since that rod is what drives your Gleebous odds.
- Keep an eye on fish weight and rarity before selling, since both factors scale the Glorp Bux payout on a Gleebous catch.
- Revisit the shop daily if the Power Source is missing, since the stock may rotate.
Troubleshooting
| Problem | What to do |
|---|---|
| The Purchase option for the Power Source is greyed out or missing | Confirm you meet the level requirement, own the Blade of Glorp, have activated Dr. Anton's D.R.E.D-7 rod quest at the Underground Music Venue, and have at least 55 Glorp Bux. |
| You are fishing in Roslit Bay but your Glorp Bux balance never increases | Only fish with the Gleebous mutation count toward Glorp Bux. Make sure you are selling Gleebous catches specifically and not just any fish from the area. |
| You cannot find Sophisticated Glorp's shop | Use the in-game GPS to navigate directly to Roslit Bay; his shop sits near where the original Glorp NPC and the Blade of Glorp quest used to be. |
