Dave The Diver Chapter 6: Puzzle Solutions
After getting the trust of the Sea People, you'll need to enter an underwater hideout to obtain a device for a new diving suit. Use the surroundings to avoid detection and reach the room with the required device. Once you have the diving suit, head to the Glacial Area and activate three switches to open the Control Room door. Solve a rotating device puzzle and match a statue's pose to progress further. Here are all the chapter 6 puzzle solutions in Dave The Diver.
Getting the New Diving Suit
After getting the new diving suit, head to the Glacial Area. You'll notice that three switches are out of reach, but the water around them is being moved by mysterious currents.
Activate the first switch, then head to the second one. To get there, you'll need to use the current that's pushing you and ride it to a platform. From there, use the Beluga to activate the second switch, which will cause a giant chunk of ice to melt and reveal a path. Go down this passage, and use a Divine Fruit to laser interact with the switches, which will melt the ice.
Navigating the Puzzle with Dave and Suwam
As you continue onward, you'll notice that Dave and Suwam are stuck on separate rocks. You'll need to control both simultaneously to navigate the puzzle. Use Dave to press the button and open the gate, then use Suwam to swim against the current to reach the switch.
This will allow both characters to exit the area. Nearby is a set of traps that will trigger rocks to fall. Dodge these to reach the mechanism. Use both characters to interact with it and pull the chain. This will allow you to proceed.
Another area has a series of stone platforms. Use Dave to lift them, then push them to allow both to advance. There are multiple of these sections, and you'll need to use the same method to continue.
That's all the puzzles in Chapter 6 of Dave The Diver.
