Treasure Ship

A Treasure Ship (also known as Coin Ship) is a large, flying vessel, similar to an Airship that appear in Super Mario Bros. 3. If Mario or Luigi ventured on a Treasure Ship, they would find dozens of coins which he could collect. Not including the ones battled at the end, there are no enemies found on Treasure Ships, but they could still fall off the ships.

Treasure Ships are summoned through a trick that can only be performed in Grass Land, Sea Side, The Sky, and Iced Land. To do this trick, one Hammer Bro. must be on the map screen and Mario or Luigi must have a coin total ending in two of the same number (other than zero) by the end of a stage. Also, the numbers chosen for their coin number must be the same as the second (from right to left; i.e. the tens digit) number of their score even after the final level tally (the player should keep in mind that 50 points per remaining second are earned at the end of the level). When Mario or Luigi returns to the map screen, the Hammer Bro. will be replaced with an item-filled Treasure Ship.

Even if the Hammer Bro. is changed to a treasure ship, it and its partner would still appear in the cabin. The same item would appear for defeating them.

Trivia

 * The Treasure Ship always contains the same amount of items, which is 168 Coins and a hidden 1-Up Mushroom near the final Warp Pipe.
 * The Treasure Ship bears a resemblance to the ship seen in the title screen of the game Shin Onigashima.
