Moink

Moinks are enemies from The Legend of Zelda: Spirit Tracks. Identical in appearance to pigs from The Legend of Zelda: The Wind Waker, Moinks wander the open areas, sometimes congreagating on the Spirit Tracks. The Spirits' Train's whistle can be used to scare Moinks away from the tracks, but if the train happens to hit one, it is brought to an abrupt stop, and the horde of Moinks begin attacking the train relentlessly.

Etymology
The name "Moink" is likely derived from oink, the sound pigs make.
