The trouble with the dolphins is they lost their way to Switzerland. They managed the Atlantic Ocean and even swam through the english channel. Instead of swimming up the river Rhine, they went south, because it was warmer, and decided to settle in the Mediteranean and no-one has seen them since. Although they say if you look carefully in the River Aar in Switzerland, you might see the last dolphin, Rumour has it that it was a meal for the ducks and swans. In other words let’s for get the whole thing, there are no dolphins in Switzerland.
