Chapter 3 of Dave the Diver: In the Jungle, titled Diving Suit of the Sunang Civilization, picks up the moment you finish helping Muna with her lake research. After you recover the last items from the deep water, Muna sets a new goal for Dave. The ancient Sunang left a diving suit inside a temple near Utara Village, and getting to it means pushing into the most dangerous, deepest part of the lake yet.
Quick answer: Chapter 3 begins the morning automatically after you hand Muna the Broken Breathing Apparatus and the glowing stone at the end of Chapter 2. Before diving deeper, upgrade to the Advanced Purification Filter (150 Doni, 3x Dinosaur Vertebra, 1x Dinosaur Skull) so you reach 950 filter capacity and a 75m depth.

How Chapter 3 starts in Dave the Diver: In the Jungle
The trigger for Diving Suit of the Sunang Civilization is the final objective of Chapter 2, where Muna asks you to bring back the Broken Breathing Apparatus and a shiny stone from the lake floor. Complete that hand-off, sleep through the night, and the new chapter opens on its own.


You know the chapter has triggered when the new objective about the temple and the Sunang diving suit appears after the morning scene. If it does not, you have not yet delivered both items to Muna, so check your inventory and return the Broken Breathing Apparatus and the glowing stone first.
Upgrade the Purification Filter before going deeper
The lake’s Hydrogen Sulfide grows more concentrated the deeper you swim, and the Purification Filter is what keeps Dave safe in those hazard zones. Each upgrade raises both the filter’s capacity and the depth you can reach, and Muna handles the work in exchange for Doni and a few materials.
To explore the temple depths in Chapter 3, the Advanced Purification Filter is the level you want. Gather the materials during your lake runs so the upgrade is ready when Muna offers it.
| Filter | Cost | Capacity | Max depth |
|---|---|---|---|
| Improved Purification Filter | 3x Dinosaur Bone Fragment + 70 Doni | 550 | 55m |
| Advanced Purification Filter | 150 Doni + 3x Dinosaur Vertebra + 1x Dinosaur Skull | 950 | 75m |

Tip: The filter is a timed meter that sits next to your oxygen gauge while you are in the lake. If it empties before you surface, the filter breaks and the Hydrogen Sulfide starts hurting Dave again, so plan each deep run around how many bars you have left.

Earning Doni for the upgrade
Doni is Utara Village’s currency, and you mainly earn it by completing missions and by running a night shift at Bancho Grill. To pass the time during the day, walk around the village, dive into the lake, or sit on the bench near Bancho until evening arrives.

At the grill, customers sit down and request dishes that Bancho prepares, and you deliver each plate before the order timer fills with red. Some guests ask for Coconuts, a separate item handled with a quick prompt where you cut the coconut open and then confirm when the white circles line up with the green ones. Befriending more villagers brings more customers in, which raises both your earnings and the grill’s rating.

Where Chapter 3 fits in the In the Jungle story
In the Jungle is a post-game DLC for Dave the Diver, and it runs across seven chapters set around Utara Village and its sweetwater lake. Diving Suit of the Sunang Civilization is the third of those chapters, sitting between the early village setup and the deeper underwater story that follows.
| Chapter | Title |
|---|---|
| 1 | The Village with Bad Food |
| 2 | Jungle Life! |
| 3 | Diving Suit of the Sunang Civilization |
| 4 | The Sea Beneath the Lake |
| 5 | Fruit of the Blue Divine Tree |
| 6 | Sea People Settlement |
| 7 | Deep Down |

Recovering the Sunang diving suit is the bridge into Chapter 4, The Sea Beneath the Lake. With the Advanced Purification Filter equipped and the temple objective active, you have everything needed to keep pushing toward the lake’s lowest reaches.
