Lemguin

Lemguin is a large sharp-billed crested penguin encountered in the games Donkey Kong Country 3: Dixie Kong's Double Trouble! and Donkey Kong Land III. Its name is a portmanteau of the animals "Lemming" and "Penguin". Lemguins are the land equivalent of Bazzas and Swoopies, other enemies which have similar attack patterns to Lemguins.

Donkey Kong Country 3
Lemguins first appear in Donkey Kong Country 3, where they only appear in one level, Lemguin Lunge, which is even named after them. In various parts of the level, an indefinite number of Lemguins jump out from holes in the snow and slide on their bellies, attempting to hit into the Kongs. In the Game Boy Advance remake, they jump straight upward before sliding on their belly.

The Kongs can defeat a Lemguin by jumping on it, hitting them from behind with a Cartwheel Attack (as doing so from the front injures the lead Kong), or by hitting them with any type of barrel.

According to the game's credits, Lemguins belong to the "Terrorfirma Tuff Guys" enemy class.

Donkey Kong Land III
Lemguins reappear in Donkey Kong Land III, where they only appear in two levels: Polar Pitfalls and Tundra Blunda. Lemguins have the same attack pattern and can be defeated via the same methods. In the Game Boy Color port, the Lemguins' sprites are colored purple.

Trivia

 * Cooligans, who are penguin enemies from New Super Mario Bros. Wii and New Super Mario Bros. U, have a similar attack pattern to Lemguins.
