Summary The kids are playing at the Atlas when Volante arrives with an invitation from Mala Malao: "I've got an amazing adventure for you!" When they meet him, Mala Malao shows them a treasure map drawn by him when he was a kid. The gang gets super excited. However, when they finally arrive at the X spot on the map, the gang deflates: it's only an old and decadent tree house, very disappointing for kids who were expecting a fantastic treasure. Mala Malao explains that the forgotten house belonged to him in his childhood; then he finds an old wooden board and gets very emotional. The gang doesn't understand what makes it so special and Mala Malao tells them to look beyond its outer appearance: the board is actually a grass sled. The five of them have fun going downhill and doing tricks on the sled. The fun increases as Mala Malao shows them other things: ordinary wood sticks that are actually stilts with springs; an old hanger and rope that he used as zip line; etc. The kids love each new discovery and, little by little, the tree house becomes something greater than they expected. Then, while Mala Malao takes a nap in his favorite hammock from childhood, the kids realize that the tree house itself is the treasure the map was pointing at. After all, treasures are not only gold coins - The gang decides to repair the tree house while he sleeps. When Mala Malao wakes up, he is moved by the surprise and says that now the "treasure" belongs to all of them.
