From the Super Mario Wiki
Lost Mangroves is the first island in Donkey Kong Country: Tropical Freeze. As the name suggests, this island is covered in mangrove trees, with many reaching enormous sizes. The island is home to many coves, forcing the Kongs to swim and introducing underwater mechanics. Some of these coves feature the remains of large shipwrecks. In addition to the shipwrecks, many plane crashes are also found on the island. This island also introduces mine carts. Many Snowmads and their ships are found here, particularly Tuckses. Other enemies include Dozies, Monocle Monicas and Punchy Paddies. The boss of this world is Pompy.
