We learn about some of the amazing contributions of animals in history. Sophie learns how Laika was the first dog in space but met a sorry end. Sophie tells the story of unsinkable Sam - the cat who was sunk three times in World War Two and served in both the German and British navies. And we learn about the brave Pigeon Cher Ami who saved hundreds of American lives in World War One.
And you can all sing along at the end with Sophie as she pays tribute to animals in history with a special song.
