The first game in the Paper Mario series (called Paper Mario 64 for the sake of differentiation), released for the Nintendo 64 in 2001 The game starts when Mario and Luigi get an invitation from Princess Peach to attend a party at her castle. When Mario goes to have some alone time with Peach, the ground suddenly shakes and the castle suddenly rises into space with all of the guests still inside. It turns out that Bowser built his castle underneath Peach's and rose both of them up into space in a giant Koopa Clown Car. Bowser then appears and reveals he had stolen an artifact called the Star Rod from Star Haven, which he uses to effortlessly defeat Mario and throw him out the window to the world below.
