Iron Goombas are Goombas first found in Super Mario Bros. NS. They are immune to every attack, even Invincible Mario. It is oddly shaped. They were originally going to appear in Super Mario Galaxy, but were cut out from the final game. These indestructible enemies made their return in Goomsday Wii as hunks of iron shaped into giant Goombas by Goomboss and his Scepter of Superiority. They served as road blocks in the Super Castles, and were only passable if Shadow Mario turned them to his side. In this case, they would walk forward (in the direction the adventurers are moving), destroying everything in their path. They can only be damaged in Piranha Palace.
