Soon the second billy goat Gruff came to the bridge. He was bigger than his little brother, and his feet were heavier. Trip, trap, trip, trap! went his feet, much louder now. "Who is that walking over my bridge?" roared the troll. "It is only me, the second billy goat Gruff," said the goat. "I am going up to the hillside to eat the sweet grass." "Oh no!" said the troll. "I am going to eat you up!" "Oh please, do not eat me," said the second goat. "I am not the biggest one. Wait a little. My big brother is coming, and he is far bigger than me." The troll wanted the biggest dinner of all. "Very well," he growled. "Go away." So the second goat ran over the bridge and up to the green grass. At last the great big billy goat Gruff came to the bridge. He was huge, with long horns and a thick beard. TRIP, TRAP, TRIP, TRAP! His heavy feet were so loud that the whole bridge shook under him. "Who is that walking over my bridge?" roared the troll. "It is me, the great big billy goat Gruff!" said the goat in a deep, strong voice. "Then I am coming to eat you up!" shouted the troll, and he climbed onto the bridge. But the great big billy goat was not afraid at all. He put his head down low and ran straight at the troll. He hit the ugly troll hard with his two great horns. The troll flew high into the air and fell down into the cold river. The fast water carried him far away, and nobody ever saw him again. Then the great big billy goat walked over the bridge and up to the hillside. Now the three billy goats Gruff were together again. They lived on the green hillside, and they ate the sweet grass every single day. They grew so big and so fat that they could hardly walk back home. And there they stayed, happy and fat, for many long years.
