The highly anticipated Heartopia × Dave the Diver limited-time crossover event (themed "No Bubbles Lost!") is officially live!
This collaboration brings the vibrant marine essence of the hit indie game Dave the Diver straight into the cozy world of Heartopia. This comprehensive guide covers the event schedule, rapid Diving Valve farming methods, and the exclusive exchange shop catalog.
To maximize your limited-time rewards, keep these key event parameters in mind:
Event Metric | Details | Notes |
|---|---|---|
Event Name | Heartopia × DAVE THE DIVER Crossover | Theme: "No Bubbles Lost!" |
Start Time | August 8 at 06:00 | Server Time |
End Time | September 7 at 05:59 | 30-day active window |
Event Currency | Diving Valves | Required for all shop exchanges |
Eligibility | All D.G. Members | Access directly via the Event Page |
To purchase the crossover items, you need to accumulate Diving Valves. Players can obtain this special currency through two main activities across the island's coastal lines:

Equip your gear and dive into the Ocean Cleanup hobby. During the event period, clearing up ocean trash and marine debris triggers bonus drops. Every successful cleanup effort rewards you with a generous amount of Diving Valves alongside standard hobby experience.

Stroll along the beaches, coral reefs, and shallow waters to gather unique Ocean Collectibles. Interacting with these limited-time environmental items gives you a high chance of looting extra event currency.
(Note: To keep progression balanced, the developers have implemented a daily soft cap. You can farm a maximum of 1,000 extra Diving Valves per day via Ocean Cleanup and Collectibles.)
If you don't have enough time to grind every day or want to get all the items immediately, you can buy them directly in the game. For a quick and safe way to buy event packages, you can top up your account through TOPUPlive to get your Heartopia Diamond instantly.

Accumulated Diving Valves can be traded at the event exchange store. The cross-over items pay heavy homage to Bancho Sushi and Dave’s iconic diving gear:
Category | Highlighted Rewards | Priority & Strategy | |
|---|---|---|---|
Limited Recipes |
| Bancho Sushi pixel dishes | ⭐⭐⭐⭐⭐ Top priority; likely missable. |
Exclusive Clothing |
| Dave's wetsuit & Bancho gear | ⭐⭐⭐⭐ Essential for fashion collectors. |
Themed Furniture |
| Retro pixel sushi bar decor | ⭐⭐⭐⭐ Best for custom marine rooms. |
No. This is a limited-time crossover event. Once the event expires on September 7, unused Diving Valves and the exchange store will become inaccessible.
No. The 1,000 daily valve cap resets every day at server reset time. Unfarmed valves do not roll over to the next day.
Go to your Event Page in the game menu. Click on the Heartopia × Dave the Diver event tab, and you will see a direct link to the exchange shop.
If you run out of time or reach your daily farming limit, you can buy extra event vouchers directly in the game. You can top up your account quickly and safely through TOPUPlive to get them instantly.
The Heartopia × Dave the Diver collaboration bridges cozy simulation and deep-sea exploration perfectly. Log in daily, clear the ocean shores, and gather your Diving Valves to secure these exclusive cross-over items before the tide rolls out!
