Moink

Moinks are cow-like pigs and the first enemies Link meets during the events of Spirit Tracks. They are very cowardly and will run away to Link's train whistle. They attack by running into the Spirit Train. They are very weak, and because of this they disappear after obtaining the Ocean rail map. Moink's name is a combo of "moo" and "oink", referring to the animals they are based off of.
