Sugar Loaf Mountain
From the Super Mario Wiki
Sugar Loaf Mountain (in Portuguese: Pão de Açúcar) is a peak at the bay of Rio de Janeiro, Brazil. During the events of the game Mario is Missing!, Luigi found a Sugar Loaf Mountain cable car that was stolen from the mountain by Koopa Troopas. The cable car is needed to get visitors to the top of the mountain. Upon delivering it back, Luigi was rewarded a prize of 2,250 dollars.
The peak also makes a cameo in both versions of Mario & Sonic at the Rio 2016 Olympic Games.
Pamphlet information from Mario is Missing!
Sugar Loaf Mountain stands on the left side of Rio's great balloon-shaped bay. Two cable cars carry visitors 1300 meters[sic] above both the city and Guanabara Bay. Once atop the mountain, visitors can get off at the lower vista and watch samba troupes perform at cliffside restaurants, or they can go all the way to the top. From that height the city spreads out below like a carpet of lights. The granite mountain got its name from Portuguese sailors who swore it resembled the cone-shaped loaves of sugar processed from Brazilian sugar cane.
