Fisch’s Drylands Update just added one of the game’s biggest expansions yet: a brand-new desert biome with Sand Fishing, fossil hunting, and a massive prehistoric predator called Terrosunder roaming beneath the dunes. A limited-time Fourth of July event runs alongside it. Here’s everything new, plus the latest codes before they expire.

The Drylands is a brand-new desert biome packed with hidden locations, collectibles, and mechanics unavailable anywhere else in Fisch. Instead of casting into lakes or ocean water, you’ll cross sand dunes, dig up buried fossils, and survive environmental hazards unique to the region. Stay alert while exploring — a massive prehistoric creature called Terrosunder patrols the dunes and becomes dangerous if you get too close.
The Drylands introduces Sand Fishing, played with a new tool called the Sand Sifter instead of casting into water. With it, you can:
This is a completely separate collection track from traditional fishing, so veteran anglers have a fresh grind to work through. If you’re also chasing rare catches elsewhere in Fisch, our Living Garden Bestiary guide covers a similarly collection-heavy zone.
Paleontologist Petri runs a new questline centered on uncovering the desert’s ancient history. Completing her objectives rewards valuable items and pushes you closer to one of the update’s biggest secrets tied to the buried creatures below the sand. Fossil collecting runs alongside this questline — a brand-new category for players chasing full collection completion.
| Weather | Effect |
|---|---|
| Dust Storm | Reduced visibility, but boosts Luck and unlocks exclusive fish |
| Torrential Rain | Floods Claypans, opening new fishing spots and different fish |
If you’re aiming to complete the Drylands Bestiary, plan around Dust Storms specifically — several catches are locked behind that weather event.
Terrosunder is one of the most dangerous additions to Fisch yet — a massive predator that moves beneath the desert and can surface unexpectedly near players. Developers have hinted at a way to eventually awaken its true form, suggesting a bigger challenge is still coming. Treat it like an active hazard rather than a catchable fish for now.
