You need to control an underwater bathyscaphe, on which you can sink very deep under water. There you will collect various objects with which you can open the doors to go into the caves, and reveal secrets in them. But in order to swim into the cave you have to make a lot of effort and logic. After all, you simply can’t open the cave in order to get into it you need to use a lot of objects that you will find at the bottom of the ocean. In the middle of the bathyscaphe will sit Scooby Doo, who controls it. Try not to swim very close to the sharks so that they do not scare you and you do not crash when you swim away from it.
