The episode starts with Kirby, Tiff, Tuff, and the Cappy kids relaxing by the beach, when all of a sudden, it gets cold, so they go to Castle Dedede to find if he bought any demon beasts. He shows them a bill that says that he can't buy anymore demon beasts until he pays his bill, so Tiff, Tuff, and Kirby decide to investigate outside. All the Cappies go with them, and they all find an iceberg, and a penguin clan called Pengi. They say they came when the village started to snow. Mayor Len and the other Cappies hold a celebration for the Pengi, but Tiff, Tuff, and Kirby investigate the iceberg. Kirby found a way inside the iceberg to a giant air conditioner so large, it froze Cappy Town. They're all caught by the Pengi. They are held hostage and the Pengi freeze everyone with their ice breath. They say they don't like to wander because they want to find somewhere cold to live, and that their home was destroyed. They invade the village and the castle, while also making Dedede and Escargoon do intensive labor, so Tiff, Tuff, and Kirby devise a plan. They say they need to pee, but they were using this opportunity to get out of the castle by dressing as Pengi. They meet up with a Pengi guard, but it was actually Meta Knight in disguise. While Dedede and Escargoon talk about being happy that Kirby is in their lives, they are freed from their intensive labour and ambush the Pengi leader. Kirby inhales his ice breath, becomes Ice Kirby, and fights him. Problem is, the ice benefits to the Pengi, so Dedede tries ordering a fire demon beast, but instead gets a hot sauce called Volcanon. Tiff calls for the Warpstar and tells Kirby to take the Volcanon to Guilwea Volcano. He does so and pours the hot sauce in the volcano while humming a merry tune, and it erupts, melting all the snow. The Pengi leave Cappy Town and the warm weather returns. While Dedede and Escargoon cool off with lots of air conditioning machines, Tiff, Tuff, and Kirby short-circuit out their machines, saying they should conserve energy like the Pengi. The episode end with Kirby jumping into a small tub of water.
