In Lhokseumawe, Indonesia, four children are engaged in an activity on a muddy beach. The foreground features a pile of dark mud adorned with numerous snail shells, some protruding vertically and others horizontally. One child, a boy wearing a gray t-shirt and red shorts, is crouched down, reaching towards the shell-covered mud structure with his right hand. His left leg is bent, and his feet are bare. Behind him, another boy in a blue shirt and dark pants is also crouching, appearing to be focused on the same activity. Further in the background, a third child, wearing dark clothing, is crouched near the water's edge, facing away from the camera. The fourth child is only visible as a shadowy figure in the distance. The environment is a beach with gentle waves rolling onto the shore under an overcast sky. The water appears murky, and the sand is wet and muddy. In the far distance, several small boats are visible on the horizon.
