Rick Nautilus. Alarm in Dolphin Lagoon

While traveling across the Pacific Ocean, Rick and his team encounter two dolphins, long-time friends of Ava. The animals are worried: something strange is happening on an island adjacent to a small atoll where the dolphins raise and train their young. It seems there is a terrible monster in the jungle, and the ground shakes from its roar. The crew of the “Nautilus” immediately goes to help. They will have to deal with the plans of the digging robots, confront old enemies, and get wet several times. And the underwater bathyscaphe will surprise everyone with its new technical capabilities.
