Federico likes to think of himself as a great storyteller, but his friends know that most of his stories are wildly exaggerated. One day Federico is telling his best friends the story of how he was in the middle of the great river the Rio Grande during a huge storm. However, once they hear that there are hackberries nearby, they rush off, leaving Fedrico's story unfinished. Angry that his closest friends had rushed off in hopes of finding hackberries instead of listening to his story, Federico stomped off in a random direction. There, he found the biggest, juiciest, most delicious berries he had ever seen! But how will he convince his friends that this time, his story isn't exaggerated?
