E-Coin Castle
The title of this article is conjectural; an official name for the article's subject has not been found, so it has been given a fitting title by the editors. If an official name is found, then the article should be moved to its appropriate title.
The World-e Castle is an area found only in World-e of Super Mario Advance 4: Super Mario Bros. 3. The castle is of unknown origin and does not contain any occupants.
When Mario and Luigi first visit the castle, the frames on the wall are empty. As levels are scanned through an e-Reader, those containing an e-Coin will have its frame indented and its level number in the white space below. As such, the castle appears to be a sort of "museum" or trophy gallery.
The castle has three floors of eight frames each, with the second and third floors (2F and 3F) opening to Mario and Luigi once the player scans a level containing a ninth and seventeenth e-Coin. The player can teleport between floors by pressing 
and 
. However, despite the game containing the code and sprites to allow this, the e-Reader's failure saw only the completion of 1F (Super Leaf, Starman, Toad, Mario, Princess Peach, Luigi, Mushroom, Fire Flower), with American players only able to collect three e-Coins (Super Leaf, Starman, Mushroom).
It is unknown if there was to be any reward for filling all of the castle's 24 frames.
Trivia
- The music played in the castle is very similar to the Mushroom Kingdom theme in Super Mario RPG: Legend of the Seven Stars.
