Popo and Nana were playing cards as they were using their snowy powers to make the snow fall more whenever it stopped, with them twirling around their hammers to get their arms some movement so their blood wouldn't freeze up.
"I'm glad we can enjoy a nice quiet time playing cards together." Popo said as he had to grab some more cards from the deck. "But why did we decide to just do this?"
"Oh it's simple." Nana chimed as she attempted to pull out a card, then shook her head and placed it back. "When you're out of ideas, just play cards."
The Ice Climber twins were quite comfortable with their card game, so they continued on as eventually ran out of cards, deciding to make new ones out of the ice they formed within their igloo.
