|Race||Goblin and Giant turtle|
|Build time||100 seconds|
These Giant sea Turtles are native to the southern seas and were captured by the Stormreaver clan. Pacified by potent spells of control, these lumbering monstrosities are fitted with watertight canopies strapped onto the backs of their shells and are used as submersible Orcish craft. By submerging under the waves, the Giant Turtles can steal upon unsuspecting enemy craft and report their position to the Horde fleet as they are visible solely to Towers, creatures of the air, and other submersible vessels. The daring Goblins who control them are dedicated to destroying enemy ships by launching hazardous, steam-driven canisters containing highly volatile liquids that can shred even the strongest of armor.
- Giant Turtles are special naval units that are invisible to all enemy units except fliers, Towers, and Submarines. They are used to destroy enemy sea buildings and any unescorted ships that cannot see them. They cannot attack enemy land units or buildings.
- Even if they cannot see them, enemy units can still destroy Giant Turtles by using the "Attack Ground" command or certain spells.
- Giant Turtles are mostly useful when the enemy is focused on an early-game rush and therefore puts off building a Gnomish Inventor. It is not prudent to build them once Flying Machines become common.
