Aristides, Wilbur and his sister Juultje investigate the spot in the forest where the boys made the fateful photograph. The boys spot an empty packet of Egyptian 'Sulellah' cigarettes and Juultje finds a large silver ring. When the boys take the photograph to the police, the officers only laugh at them. Meanwhile Grandpa gets in trouble when a little boy spurs him on to protest a shop that sells seal-fur coats. Wilburs father asks the boys to pick up a crate of 'Poeff' lemonade for which he is to come up with a new slogan. In the supermarket, they spot the scary man buying a packet of Sulellah.
