Contempting Ice Climber

Popo and Nana were sitting on a floating iceberg as they looked at each other, with the two having recently conquered a nearby snowy mountain that had collapsed on them earlier.
Popo: (while stretching) Quick question.
Nana: (letting out a loud yawn) I'm listening.
Popo: How come we never climb anything else?
Nana: (picks her nose) Huh?
Popo: I mean, yeah we're suited to the snow and ice, but... isn't there anything else to life besides mountain climbing?
Nana: (farts and burps simultaneously) Mah boi, you gotta learn to not worry. Doing mundane things... that is a feat everyone does.
Popo: I... err... guess you're right.
Nana: (sneezes) Of course I'm right. I'm the brains.
The pink robed girl ice climber then began hiccuping, which proved to be stupid as the glacier they were on them broke apart, causing the twins to fall into the freezing lake and turn into solid blocks of ice.
