Crocodile Isle

Crocodile Isle is the place Diddy Kong and Dixie Kong adventured through in Donkey Kong Country 2: Diddy's Kong Quest and Donkey Kong Land 2, presumably the place of origin of the Kremlings.

In contrast to Donkey Kong Island or the Northern Kremisphere, which are both beautiful, paradise-like locations, Crocodile Isle is a gloomy and dark place. Almost all of Crocodile Isle is shrouded in fog; swampland is also found almost everywhere on the island. The coast of Crocodile Isle is almost constantly battered with rough currents, which over the years have wrecked several ships on the island's rocky coast or swamped them in the island's bogs. Several parts of the island are volcanic, and the top of the island, where K. Rool's Keep is located, is frozen over.

Crocodile Isle is apparently in close proximity to Donkey Kong Island, as said island can be seen from both the remains of the Gangplank Galleon and K. Rool's Keep. Located inside Crocodile Isle is the Kremling Lost World, the apparent birthplace of the Kremling species. The Lost World also contains a altar-like structure built into an crocodile-shaped volcano called Krocodile Kore, which serves as the island's core. The island has a massive Zinger and Bramble infestation.

Prior to Donkey Kong
According to Wrinkly Kong, this island was explored for the first time by Cranky Kong where he has all the knowledge here. This fact also explains by Cranky himself about his knowledge from Lost World and Kremkoins role. Some members of Kong Family as Dixie Kong and Funky Kong mentioned the name of the island only, but never explored before.

Donkey Kong Country 2: Diddy's Kong Quest
During the events of Donkey Kong Country 2: Diddy's Kong Quest and its pseudo-port Donkey Kong Land 2, Diddy and Dixie Kong adventured through Crocodile Isle in their search for the recently kidnapped Donkey Kong. If players manage to obtain the "best" ending in Donkey Kong Country 2, Kaptain K. Rool will end up clogging the volcano in Krocodile Kore, causing an explosion which will cause Crocodile Isle to sink into the sea, while K. Rool escapes on a raft, laughing. In the GBA version, however, K. Rool's clogging of the volcano does not cause the island to explode.

Donkey Kong Country television series
Though Crocodile Isle never directly appeared on the Donkey Kong Country animated series, several Kremling characters such as King K. Rool and Kaptain Skurvy would sometimes mention the "swamps back home".

Donkey Kong 64
In Donkey Kong 64, a newly constructed Crocodile Isle appears, now equipped with powerful weapons to aid in the destruction of Donkey Kong Island.

Bumm-Badabumm im Urwald
In the obscure Donkey Kong comic Bumm-Badabumm im Urwald, Crocodile Isle never made a direct appearance, though several locations ventured through in the comic, such as a Krochead and a crashed ship-filled swamp, along with the "Lost Land", are obviously based off areas of Crocodile Isle.
