The first player controls Popo, a boy wearing a blue Eskimo parka, while the second player controls Nana, a girl wearing a pink Eskimo parka. The only tool they carry is a wooden mallet to carve openings in the ice above and to club enemies. Each mountain level consists of eight layers of colorful ice and a bonus stage. Standard, dull ice blocks pose no threat other than an easily disposed of barrier and platform. Square ice blocks with higher detail are indestructible forcing the player to take another path
