Moinks are pigs with cow-like spots, and are one of the first enemies Link meets during the events of Spirit Tracks. They are very cowardly and run away to Link's train whistle. They will become aggressive if the train crashes against it, or one is shot with the Cannon. When provoked, the Moinks turn red and attack by running into the Spirit Train. They disappear after Link has obtained the Ocean Rail Map.
- Moink's name is a combo of "moo" and "oink", referring to the voices of animals they are based on.
