Popo and Nana, collectively known as the legendary Ice Climbers, are mountaineers. One day, a condor invades and steals their vegetables, such as cucumbers, eggplants, turnips, mushrooms, carrots, pumpkins, corn, cabbages and more. This prompts the Ice Climbers to persistently pursue the condor by scaling 32 giant glacial mountaintops located in the Icicle Mountain, which is the world's largest mountain.
Along the way, a number of dangerous enemies from the wildlife reside in the mountains to antagonize the Ice Climbers: those enemies include Topis, Nitpickers, and white Polar Bears.
Upon reaching the summits of the glacial mountains, the Ice Climbers retrieve their veggies laying around the floor, and after so, Popo and Nana reach the top of the mountain to grab onto the condor's talons, thus progressing to the next mountain.
After conquering all of the mountains and retrieving all of their stolen veggies from the condor, the Ice Climbers return home with them.
