Storyline
Background
Pre History
A mallet-swinging duo from the icy peaks.
Super Smash Brothers
Brawl X
The one in blue is Popo, and the one in pink is Nana. They use their incredible jumping powers and hammers to break blocks and climb to the summit. They grab veggies, and if they can catch the condor at the end, they conquer the mountain. Other than breaking blocks, their hammers are good for sending foes flying, climbing down from blocks, and destroying icicles.
Deluxe Melee
That's Popo in the blue and Nana in the pink. These two stars of the game Ice Climber have scaled many an icy summit in their mountaineering careers. Back in their glory days, they chased eggplants, cucumbers, and other vegetables that inexplicably fell from frosty summits when a condor reigned supreme. They're rarely seen apart.

Fun Facts
They Fell Off A Mountain
Project lead Masahiro Sakurai has gone on record as saying that, while his team got them working perfectly in the Wii U version of Super Smash Bros., the Ice Climbers were not functioning as expected in the Nintendo 3DS version. Since the two versions needed to have identical rosters, the pair was cut from both.

A glitch in the 3DS version will have the audience chanting Popo and Nana's names instead of the player's, sometimes.
