Meanwhile, Team Rocket, overlooking the Pokémon Center from a nearby cliff, complains about the cold draft. They leave to find its source and soon come upon the large building Joy described. They set about their evil deeds as the scene cuts back to Brock in the Pokémon Center. Brock continues to dream of Nurse Joy, and mistakenly shares a kiss with Jynx as she cares for him. Nurse Joy notices a rapid rise in cavern temperature, and goes to the building with Ash and Misty to investigate. All three travel by sled driven by Piloswine. Upon their arrival, the group sees that the structure has been reversed, heating the cave and cooling the jungle outside. This puts both sides in danger, so the group runs outside to find the cold air pipe, but immediately falls into a pitfall dug by Team Rocket.
Team Rocket declares their plan to steal the Ice-type Pokémon before running off. Ash and the others climb out of the hole with help from Bayleef. Knowing they have to get the pipe back in the cave, Ash commands Bayleef to use Vine Whip to grab the pipe. They then pull on Bayleef's vines as hard as they can, and the pipe is restored to its original place. The scene cuts to Brock lying in bed in his sickly state, and he gets up out of bed. He notices Team Rocket outside the Pokémon Center; they have set up a bunch of heaters to weaken the Ice Pokémon there. They scoop up all the Swinub and Piloswine there, and then Jynx appears. She attempts to stop them, but Team Rocket points a heater right at her, and Jynx collapses.
Brock, in his weakened state, appears to confront Team Rocket. Brock sends out his Geodude, while Jessie sends out her Arbok. Geodude uses Tackle, but this has no effect on Arbok, and the snake Pokémon retaliates using Headbutt. Geodude is sent flying into Brock, and Jessie commands Arbok to use Wrap on both of them. Arbok wraps them with its tail and slams them into the ground. Brock has been defeated, and Team Rocket proceeds to steal Geodude. Just then, Ash, Misty, and Joy appear. Misty and Joy tend to Brock, while Ash takes care of Team Rocket. He sends out Totodile, and Jessie once again uses her Arbok, and James sends out Victreebel. Misty joins in too, sending out her Corsola. She commands it to use Tackle, and James, under attack from Victreebel, is sent flying. Meanwhile Totodile uses Bite on Arbok. Jessie then sends forth Wobbuffet. Corsola uses Tackle on Wobbuffet, but he uses Counter and sends Corsola flying. Totodile uses Water Gun on Wobbuffet, but he counters this too and Totodile and Corsola are defeated.
Meanwhile, the cold air enters the battleground. Pikachu then uses Thunderbolt on the heaters, and the Ice Pokémon are revitalized. Jynx and Piloswine use Powder Snow on Team Rocket. Joy commands Jynx to use Lovely Kiss on Wobbuffet. For their final effort, Joy commands Jynx and all the Piloswine to use Blizzard, instantly freezing Arbok, Victreebel, and Wobbuffet. Pikachu then delivers the final blow using Thunder, blasting off Team Rocket. Later, Nurse Joy thanks Ash and his friends for helping her to save the Ice Pokémon, and Brock's fever is now gone. Ash and his friends leave Joy and the Ice Cave Pokémon Center. They have now arrived at the end of the Ice Cave, and they come across Blackthorn Lake. Brock informs Ash and Misty that Blackthorn City is on the other side of the lake, and they rush towards Blackthorn City and Ash's final Johto League Gym.

This episode was skipped in the dub because of the prominence of Jynx, whose design at the time was considered by some-most significantly in the United States-to be an offensive racial stereotype. Jynx had appeared in previous episodes and another future episode in this design, but 4Kids were able to cut Jynx's appearance, as those deletions did not significantly affect the storyline of those particular episodes. That was not the case with this episode, as Jynx is one of the main characters in this episode, and 4Kids knew it would be impossible to remove Jynx entirely for this episode and still have the story make sense. As a result, 4Kids eventually decided to skip the episode in its entirety. Also, three previous episodes (Holiday Hi-Jynx, Stage Fight!, and The Mandarin Island Miss Match) that were originally dubbed and aired normally, were later removed from Pokémon TV and the re-release of the Orange Islands DVD box set because of this controversy. Jynx wouldn't appear again in a dub episode until Mean With Envy, where it finally appeared in the redesign it was given due to the complaints leveled against it.
Taiwan, Hong Kong, and South Korea are among the only areas outside of Japan to have aired the episode, as Asian dubs are based on the original Japanese version.
The Ice Cave in this episode is not named こおりのぬけみち Ice Path, as it is in the games, though its location as the gateway to Blackthorn City indicates that it is indeed the Ice Path.
