The kids play pirates when Volante arrives with a map to the Legendary Treasure of the Lost Cave. "It's the perfect adventure, sailors, here we go!". When they arrive at the island, they notice some jumping creatures that run away when they approach. The gang follows the map till they get to a passage filled with Venus Flytraps. Nearby, there are some dry tree branches and Dino has an idea: use them as stilts to walk past the plants. When they approach the branches, more creatures jump away. After they leave the dangerous plants behind, they find the entrance to the Lost Cave. By its side, they notice that one of the jumping creatures was trapped by the plant: its leg is stuck. By tickling the plant, they manage to free the creature, who run away as soon as it got released. Dino and his friends enter the Lost Cave. There, they face some challenges until they get to a final chamber where a precipice with water on its bottom separates them from the Legendary Treasure, and the only way to get to it is by an old and narrow stone bridge. Dino, Kika, Cacau and Lip try to balance along the narrow bridge till they get to the treasure chest. Lip brags about it: "Legendary? It was easy!", but when he lifts the chest up he loses balance and bumps into a stone, which hits another stone, and so on, till the whole cave is quaking and rocks fall all around. When they run towards the exit, Dino stumbles and falls into the precipice. But, just when everything seemed lost, the creature they saved appears to help Dino. And it's not alone. Three other creatures alike come with it. Mounting the creatures back, the kids hop from stone to stone till they reach the exit. Phew. Outside of the cave, the gang thanks their new friends, that hop with joy and then leave. Another adventure is completed, now it's time to enjoy the treasure.
