In Dave the Diver, apart from the boss enemies encountered during the main storyline, there are also some hidden bosses that can be challenged under very special circumstances, providing players with a more thrilling underwater combat experience. The following guide on hidden bosses in Dave the Diver will introduce four of these hidden bosses and provide methods to defeat them. Players who wish to challenge them may want to learn about them first.

1. Truck Hermit Crab
It is an oversized hermit crab covered in a truck, which can be encountered in the vortex during the first stormy night. Conventional attacks have no effect on it; only by picking up oil drums scattered on the ground and throwing them at it can you deal damage and defeat it.

2. Mantis Shrimp
This mantis shrimp, wearing boxing gloves, exists in the vortex at a depth of about 30 meters during the stormy night. It has a very fast punching speed. You can hide under the copper balls on the map to avoid all its attacks, then attack its eyes when it gets tired.

3. Klaus
Klaus is a giant great white shark. When it appears, an old woman will communicate with the player and provide information about Klaus. Then, you can find it in the vortex during the rainy night. Its combat strategy is quite conventional: dodge its attacks and use high-damage ranged weapons to hit it; there are not many tricks involved.

4. Lucas
During the stormy night, there is a chance to find a vortex and enter the challenge map for Lucas. It is a monster that is half-shark and half-octopus, moving slowly and attacking players with its octopus tentacles. Occasionally, it emits water waves from its octopus body or performs long-range charges. It is suitable to take it down slowly using long-range weapons.
The four bosses introduced in the above guide on hidden bosses in Dave the Diver are quite unique in the game. After understanding how to deal with them, if you want to challenge them, you might as well start their trials and experience the thrill of fighting these fierce underwater creatures.
