(Yes, this story is going to be messy: The first location was flooded and the second location was going to be build on, within a month after placing it. I wonder )
You walk on the beach and pick up a shell. Another shell. And another shell! Before you know it your hands are full and you ask an adult to help you holding them. They give you a cotton bag which is huge! Your shells go in there and you pick up more and more. When you are at home you put them in your box, together with the shells of previous walks. Shells are cool.
