Squall Hammer.

Squall Hammer is a move that the Ice Climbers can perform in the Super Smash Bros. video games, first appearing in Super Smash Bros. Melee and later reappearing in Super Smash Bros. Brawl. It's the characters' side special move and will cause the duo to come together and spinning around while swinging their hammers. If Nana is not with Popo, then the move will not be as effective.

When Nana has been defeated, the move can be a good attack for Popo to perform to get back to the stage, as the move Belay is virtually useless when alone. The move can be traced back to the fact that the duo used hammers in their NES debut Ice Climber, though the move itself is only used in the Super Smash Bros. games.
