Pipe Land Treasury

The Pipe Land Coin Treasury is an underground treasury that holds all of Pipe Land's money. It is entered from the Underground Maze of Pipes.

In The Adventures of Super Mario Bros. 3 episode Misadventure of Mighty Plumber, Bowser and Mighty Plumber broke into it through the Maze, when Mighty Plumber had been convinced that Mario and Luigi were trying to steal it, and they had to get all the Coins inside to Castle Koopa.

Once King Koopa got the money, he ran off and locked Mighty Plumber inside, when a security system consisting of a flood came out. Mario and Luigi appeared and helped him break out, and they were able to stop Koopa from getting away with the Coins.
