Dinosaur Friends. The Giant Octopus

Once, Papa Rex told Rasmus and Trim about a ship that sank in Black Bay. This ship hides a treasure, but you must never go there: the treasure is guarded by a giant octopus. Despite the prohibition, Trim took Papa Rex's old raft and launched it into the water — just to try it out near the shore. Of course, this was just the beginning, and soon the raft was carrying Rasmus and Trim across the waves of the Great Lake to Black Bay!
