## Explore Bubbly Basin: Wave 1 Highlights
### Underwater World & Gameplay Adjustments
The centerpiece of Wave 1 is the Bubbly Basin, a beautifully rendered sunken village beneath the ocean’s surface. Players explore more than just submerged streets: Water-type Pokémon play a vital role, enabling growth of crops like watermelons and powering environmental fixtures such as streetlights and bubble machines via their “Generate” specialty.
The Surf move also gets reworked for improved underwater traversal. Players can swim alongside Water-type Pokémon—especially Manaphy—and dive into glowing coral pathways leading to mysterious deep-sea trenches filled with secrets.
### Base Customization & Building Upgrades
Wave 1 adds buoyant blocks, enabling construction of multi-layered underwater bases. For deeper customization, players can build a Sharpedo submarine—functioning similarly to a Secret Base—which lets them design their own mobile aquatic hideaway.
### New Items, Outfits, & Recipes
Fresh customization options arrive through new outfits and decorative accessories. Culinary creativity expands with smoothie recipes. Even the classic Surf move gets an upgrade, adding depth to both combat and exploration mechanics.
