The three billy goat brothers - the youngest, middle, and oldest - were searching for green grass to eat but could not find any. They came upon a field of green grass across a bridge but a mean troll lived under the bridge and wanted to eat the goats. The youngest and middle brothers escaped by mentioning their bigger brother, and when the oldest brother confronted the troll, he convinced the troll to be friends rather than eat him. The three goats and the troll, now called Mr. T., lived happily ever after in the forest.
