Mario was about to walk to the Koopa Cruiser until Toadsworth caught up to him and brought the Suitcase too him. Meanwhile, Luigi was mistaken to be part of the Koopa Cruiser. Bowser instructed Mario and Luigi to press to open their suitcase and arrange their stuff.
Mario and Luigi went pass by Bowser's minions having passports, the photographer halted Mario and Luigi. He instructed them to open their Suitcase and he checked through the Suitcase and realized that they do not have passports and allows them to cut in line.
The Suitcase was used for different items and the Beanbean Map.
