During a big storm, Dokko thinks that the energy it produces is being wasted, and offers Pin to harness it somehow to make an endless day. They both make a satellite dish-esque structure to capture the lightning with it, but the energy ends up being too strong, releasing a huge energy wave into the atmosphere, which causes Earth to change its magnetic poles. Due to this, it starts snowing, eventually culminating into endless night. Pin and Dokko then use energy to light up the valley, but it fails to work. Krash and Chiko, who are annoyed by this, ask Dokko how long will it be until the sun shows up again, to which he estimates in about 3 to 5 months' time.
During this time, Krash and Chiko do everything to keep themselves warm and supply themselves with food, but the blizzard gets stronger each day. Once they run out of warmth, they go to the closet to discover plenty of glow worms, which they use to light up Krash's house. It's only at this moment when the polar night finally comes to an end. Dokko asks the two if they are going to sleep, to which Krash replies that they're waiting for the sun to go down. Too bad the two are unprepared for the polar day...
Tropes:
- Apocalyptic Log: August 1. It's been almost 30 days with no sunlight, no variation in the weather. Perhaps we were foolish to try and harness the power of lightning and make it endless day. Doing that is trying to build Krash's brain with math. Some things just aren't meant to fit, and now we're paying the price. Now instead of endless day, we have endless night, and I'm not even nocturnal! What gives? This is the last time I listen to Dokko.
- Borrowed Catchphrase: When Krash and Chiko find the glow worms, Chiko acquires Dokko's manner of speech while proposing they use the glow worms for light. He then stops, saying that he got out of character. The English dub omits this line.
- Bittersweet Ending: KikoRiki were able to survive months of polar night, but the Earth's magnetic poles are still inverted and it is completely unclear how to fix it.
- Endless Winter: The highlight of the episode.
- Hamster-Wheel Power: Dokko tries to light up the track using this trick, but he ends up being electrocuted and he rolls away with the wheel.
- Harmless Freezing: Dokko is completely okay with being frozen in place for 5 months.
- Here We Go Again!: After the polar night is over, Dokko mentions the polar day will be replacing it for a couple of months.
- Human Popsicle: Dokko gets frozen in the ice next to Krash and Chiko's house, but gets unfrozen by the time the polar night is over.
- Magnetism Manipulation: Pin and Dokko accidentally change the Earth's magnetic field, which causes the polar night.
- Wintry Auroral Sky: Dokko invites his friends to admire the beautiful aurora borealis.
