Treasure Ship

A Treasure Ship, or Coin Ship , is a wandering Hammer Brother that has been turned into a coin-filled airship that appears in Super Mario Bros. 3. If Mario or Luigi venture onto a Treasure Ship, they will find tons of coins that they can collect, plus a Hidden Block with a 1-Up Mushroom (which is blue in the NES version). Not including the ones battled at the end, there are no enemies found on the ships. However, the player can still lose a life either by getting crushed by the scrolling screen, falling off the ship, or letting the timer run out. If a player dies while on board a Treasure Ship, it reverts back to the original enemy.

At the end of the ship, two Boomerang Brothers are fought. The reward for defeating them would be whatever item the Hammer Brother that got replaced by the ship would have normally given (i.e. a Starman for Grass Land, a Hammer/Starman for Water Land, a Magic Wing/Starman/Music Box for Sky Land, and a Hammer/Jugem's Cloud/Starman for Ice Land).

Locations
Treasure Ships are summoned through a trick that must be performed by following a specific method:


 * The player must be in either World 1: Grass Land, World 3: Water Land, World 5: Sky Land or World 6: Ice Land.
 * A wandering Hammer Brother must be on the world map.
 * Mario or Luigi must finish a stage with a coin total ending in a multiple of 11 (zero does not count).
 * The tens digit of the player's score must match the multiple of 11 (i.e. if the coin total is 11, the tens digit must be 1, if the coin total is 22, the tens digit must be 2, and so on).
 * As each second left on the timer will award the player 50 points, the timer must be stopped on an even number so that the number of points received is a multiple of 100. Alternatively, an odd number will work if the score is 50 points off from the correct multiple.

For instance, if the above criteria are met, and the player ends a stage with 44 Coins and a score of 0246240, they will successfully trigger a Treasure Ship. It should be noted that this trick will only work once in any given world.

If this trick is performed again while a Treasure Ship is on the map, it will revert back to a Hammer Bro.

They cannot be found in World 7: Pipe Land or World 8: Dark Land, due to there not being any Hammer Bro. enemies or related enemies. They also don't feature in World-e, due to the nature of that world.

Trivia

 * The kanji character on the sail of Treasure Ships is "宝", which means "treasure" in the Chinese and Japanese languages.
 * Barring the prizes upon beating the two Boomerang Brothers, 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.
 * A golden airship similar to the Treasure Ship makes an appearance in New Super Mario Bros. 2 as part of World 5-A.
