Given this article on Donkey Kong Country 2, who is the villain of the plot and where does the story take place?

Context: Some time after Donkey Kong Country, Donkey Kong is relaxing on the beach, until he is ambushed by the Kremlings. He gets kidnapped and brought to Kaptain K. Rool, King K. Rool's moniker in this game, who then demands the Banana Hoard he unsuccessfully tried to steal in the previous game for a ransom from the Kongs. Instead of complying, Diddy Kong and his friend Dixie resolve to go to the Kremling's home island, Crocodile Isle, to rescue Donkey Kong. Together, they travel through Crocodile Isle and are helped on their way by an assortment of animals to defeat Kaptain K. Rool. Diddy and Dixie eventually battle and defeat K. Rool, releasing Donkey Kong in the process. K. Rool manages to escape though, and shortly after, Diddy and Dixie confront him in the Lost World, a secret area powered by a geyser at the heart of Crocodile Isle. They once again defeat K. Rool, who is hurled into the geyser, causing it to clog up and explode. The explosion causes all of Crocodile Isle to sink, as the Kongs watch K. Rool escape on a small sailboat.

Answer: Kaptain K. Rool is the villain and kidnaps Donkey Kong. The story takes places on the Kremling's home island, Crocodile Isle.
