Fisch: How to Get the Power Source for Dr. Anton's DRED Quest

Fisch is a fishing game on Roblox, and the Power Source is sold by Sophisticated Glorp in Roslit Bay for 55 Glorp Bux. You earn Glorp Bux by selling fish with the Gleebous mutation. The item only appears in the shop once you reach level 800 and start Dr. Anton's D.R.E.D-7 quest.

Reach Level 800 and Start Dr. Anton's D.R.E.D-7 Quest First

Two requirements have to be met before the shop lists the Power Source for purchase. Your character must be level 800, and you must start Dr. Anton's D.R.E.D-7 rod quest at the Underground Music Venue. Check both before you plan your trip, because the purchase option stays hidden until both are done.

The quest is the reason the item matters. D.R.E.D-7 is a rod you unlock by completing Dr. Anton's questline, and the Power Source is the key ingredient for finishing the D.R.E.D-7 rod quest.

Find Sophisticated Glorp's Shop in Roslit Bay Using GPS

Sophisticated Glorp's shop is in Roslit Bay at GPS coordinates -1716.2, 155.0, 502.7. Use the in-game GPS to navigate to that spot instead of searching the area by eye.

The same character handles both steps in this chain: selling your Gleebous fish and buying the Power Source. You only need to find this one spot.

Catch Gleebous Fish Around the Crashed UFO in Roslit Bay

Gleebous is a mutation, so it can appear on different kinds of fish rather than being a fish of its own. You can catch it in the waters around the crashed UFO in Roslit Bay.

If you have a Fish Radar, turn it on and cast into the light green area around the UFO.

Two rod features help. A rod with the Mutated enchant raises mutation chances, and a rod with a higher Lure stat reduces the wait for bites, which gives you more tries per minute.

Glorp's dialogue menu offers to sell Gleebous fish for Glorp Bux.

Sell Gleebous Fish and Buy the Power Source for 55 Glorp Bux

Each sale pays based on the fish's rarity and weight, so bigger and rarer catches get you to 55 faster.

Talk to Sophisticated Glorp and select "Sell my Gleebous fish."
Keep selling until your Glorp Bux total reaches 55.
Select "Show me your shop," then choose Purchase.

The trade uses your 55 Glorp Bux and gives you one Power Source.

Glorp's shop lists Power Source for 55 GB, equivalent to 55 Glorp Bux.

FAQ

Can I get Gleebous fish from the Appraiser instead of fishing?

No. The Appraiser can't produce the mutation, so appraising an ordinary fish won't turn it into a Gleebous fish.

What does a Gleebous fish look like?

The mutation turns the fish neon green and adds green particles around it. That makes it easy to pick out from your ordinary catches.

Do I need the Blade of Glorp rod to buy the Power Source?

No. The purchase only asks for level 800, the started quest, and 55 Glorp Bux. The Blade of Glorp rod does help you catch Gleebous fish because it raises your chance of landing one, so it's useful for farming them, but you don't need it to buy the item.
