One summer day a dolphin named Diver was jumping out of the water with his family enjoying the sunshine. At the same time a girl named Shelly was diving under the water and saw the dolphins and tried to get a closer look, but had to go up for air and when she came back down they were gone.

After that Shelly went home to play and eat, but she kept thinking about the dolphins so she asked," Mom can a dolphin disappear?" Mom replied, " Maybe if it swims really fast." Shelly thought that over and maybe she was right, but maybe not.

At that time Diver was heading home too and was wondering about going on a adventure across the sea, but he had to get approval, from the whale Aquatic.

So after he got approval from his parents he began to head over to Aquatic's house. When he got there he told the whale his plan and he got approval, but it expired in five days.

Back at home Shelly had to get permission to go on a team diving trip for five days

Shelly gulped as she walked into the room and slowly asked her parents for permission. After a talk they said yes if she stayed alert.
