Peter Grillin is one of the FischFest NPCs in Fisch, and his quest trips up a lot of players because the objective looks vague at first. People walk up with backpacks stuffed with event catches, try handing over random fish, and nothing registers. The fix is simple once you know the one fish he actually wants.
Quick answer: Catch 3 Barbecue Bass and hand them to Peter Grillin. No other fish counts toward the quest, even rare event catches.

The only fish Peter Grillin accepts
The quest checks for one specific catch, and that catch is Barbecue Bass. Handing over any other FischFest fish does nothing, which is exactly why the quest feels broken when you guess. Once the right fish is in your inventory, the turn-in works immediately.
You need three Barbecue Bass in total. After all three are caught, return to Peter Grillin and hand them over to clear the objective.

Barbecue Bass isn’t one of the rarest FischFest fish, but the right conditions cut down the grind a lot. Stacking these factors together gives you the best odds of pulling three quickly.
| Condition | Why it helps |
|---|---|
| Tropical Sun weather | One of the strongest FischFest weather events; many event fish, including Barbecue Bass, appear more often. |
| Night time | Barbecue Bass has a stronger nighttime spawn, so fishing after sunset beats grinding all day. |
| Summer season | FischFest is a summer event, and Barbecue Bass performs best under Summer conditions. |
| Magnet Bait | Improves overall fishing efficiency and reduces time spent searching for the required fish. |
Fastest way to finish the quest

How to confirm the quest is complete
When you turn in the third Barbecue Bass, the game registers the objective and rewards you on the spot. If nothing happens at the turn-in, the most common reason is that the fish you’re holding aren’t Barbecue Bass, since the quest ignores every other catch.
Peter Grillin quest rewards
Completing the turn-in pays out Sunshells, the main FischFest currency. Sunshells are valuable because they buy limited-time items from the event shop, including event rods, cosmetics, relics, furniture, special collectibles, and other FischFest-exclusive rewards.
Even small turn-ins like this one are worth doing, since every Sunshell pushes you closer to unlocking more of the event store before FischFest ends.
