The Ice Climbers were literally farting around on Tomodachi Life Island since they were getting bored of waiting for things to happen so they made even frozen solid so they could have an excuse of sliding around and having fun smashing things up with their wooden mallets.
"Aww yeah!" Popo said to Nana while he twirled around in an energetic manner. "We should have been doing this earlier!"
"You definitely can say that again!" Nana laughed while playfully fanning her frosty farts. "Guess we just got carried away with letting boredom get to us a bit too much-"
Suddenly they both bumped into the R.O.B. who was larger in size but back to his familiar form firing a giant laser at the Ice Climber twins that caused fire to melt away the ice and snow.
