This is one more story by Adeilson Salles. It addresses an important topic for children: the freedom to act and the consequences of one's choices. It introduces Eleoterio, an irritable frog who gripes about his living situation because he doesn't want to keep on living in the swamp and eating the same old insects. Do you know what Eleoterio wants the most? What his greatest dream is? He wants to travel ... to travel ... and visit what the title says – THE BIGGEST SWAMP IN THE WORLD. By following Eleoterio's adventures and the good and bad choices he makes along the way, children will appreciate his persistence in looking for happiness and the results of his choices.
