The Tilted Tower is an item that only appears in the NES release of Mario is Missing!. It serves as the support for the roof of Montreal's Olympic Stadium; incidentally, it is called the Montréal Tower in reality and not the Tilted Tower. The entire tower gets stolen by a single Koopa Troopa when a group of them storm Montreal, and it gets taken back by Luigi and placed in his pockets. He then shows it to various people within the city, all of whom recognize it while also spouting off trivia facts about the Olympic Stadium. Luigi ultimately takes it to the stadium's information booth, proves that the Tower is genuine to the Curator, and returns it to its rightful place.
