Captain Sharky. Adventures in the Wild West

In search of adventures, Captain Sharky and his brave pirate crew set off to America. They find themselves in the Wild West and meet a boy Indian named Anoki. The Indians of his tribe are very worried: it hasn’t rained in the plains for several weeks, and they are suffering from a severe drought. Moreover, pale faces have appeared on Indian lands, mining gold in the headwaters of the river, poisoning the water and animals in the process. To save their tribe, the Indians decide to attack the pale faces and drive them from their land.
Captain Sharky is horrified: he realizes that the Indians with their spears and arrows have no chance of defeating the pale faces, armed with rifles and pistols. Will he be able to prevent the clash and rid the Indians of the brazen invaders?
