Tank

Tanks are just like the Cannon Boats, only they are on tanks in the Fire, Snow, and Forest Realms. However, they only appear in the Forest and Snow Realm if there aren't any Dark Trains or Armored Trains. These are just like the boats and if Link is carrying a passenger (and the Pirate's Prisoner has been rescued from the Pirate Hideout), a larger Tank similar to a Pirate Ship will come attempting to kidnap the passenger.
