Popo and Nana would never have found themselves doing something as weird as kidnapping a bunch of baby seals... but why were they doing that is because the Ice Climbers just found them waiting around in a sinking ice float and they just had to save them. Course what they didn't know is that there were polar bears in pink shorts and sunglasses who were looking over the seals, with the twins barely escaping their grasp, not expecting such a polarizing reaction.
"I never would have known that bears would be protective over other species, sis!" Popo yelped.
Nana gulped. "Guess that has to do with them being bigger than a lot of things their size, bro!"
Eventually the Ice Climber pair smashed through a bunch of frozen blocks, only to reach a point so solid in ice that they had no choice but to freeze themselves in snow to prevent the polar bears from tearing them apart, freezing up the seals along with them. The polar bears in question were greeted by Popo and Nana farting at them, or at least an attempt at doing so due to the fact that they were encased in the ice that they themselves made. So what would happen now...? Who knows...!
