Ice Climbers

The Ice Climbers were the stars of an early Nintendo NES title of the same name, which had Nana (the pink) and Popo (the blue) venturing up an ever scrolling mountain in their quest to defeat an evil condor. The enemies they encountered are almost exactly the same as found in the level in "Super Smash Bros - Melee" for the Gamecube, such as polar bears and strange walking kiwi fruits. Most people had no idea who they were when Smash Bros was released and it still remains a mystery why Nintendo chose to include these two enigmatic characters.
