Once upon a time, in a deep forest lived a small family of Edmontosaurus dinosaurs. Edmontosaurus dinosaurs were large and strong; they ate just plants and shrubs, and lived together in large groups. The youngest in the group, Billy, was a naughty dinosaur who loved to play with his friends. One day, as Billy was playing near a lake, one of his friends fell into the water and was struggling to keep his head above the surface. Billy was scared of water and never used to go near it, but seeing his friend in danger, he jumped right in. After a lot of struggle Billy finally managed to rescue his drowning friend. Once out of water, the friend thanked Billy and everyone in their large family was filled with pride that Billy overcame his fears and showed immense courage when it was the most necessary.
