It can take you into a wonderful undersea world. You will find many strange animals in the sea. Some are as large as a school bus. Many sea animals give out light in the dark and some have sharp teeth. During the day, there is enough light. Here, under the sea, everything is blue and green. When fishes swim nearby, you can catch them with your hands. When you have bottles of air on your back, you can stay in deep water for a long time. However, you can't dive too deep.
