From the Super Mario Wiki
Europe, or rather just the Louvre, appeared in an episode of The Adventures of Super Mario Bros. 3, "7 Continents for 7 Koopas". When Bowser tried to conquer the entire Real World, he put Kootie Pie Koopa under control of Europe. Kootie Pie used her Magic Wand to turn all of the Louvre's famous paintings, such as Leonardo da Vinci's Mona Lisa, Sandro Botticelli's The Birth of Venus, and Marcel Duchamp's Nude Descending a Staircase into the Mona Kootie, the Birth of Kootie, and Kootie Descending a Staircase.
Mario later stole Kootie Pie's Magic Wand and used it to make The Birth of Kootie flood the Louvre, driving Kootie Pie away. Ironically, this could have also damaged the artwork in the Louvre.
Europe was later visited in the final two episodes The Adventures of Super Mario Bros. 3; "The Venice Menace" and "Super Koopa". These episodes mostly took place within the European cities of Venice and Paris respectively.
