Gold follows Silver to the Lake of Rage. Looking for him, Gold is surprised by a group of Gyarados thrashing around in the water. The locals flee, but Gold spots Silver running towards the lake. Nearly crushed by a glancing attack, Silver tells Gold that there are strange radio waves in the area, forcing the wild Pokémon to evlove. Silver flies off to find the source of the radio waves, leaving Gold alone to deal with multiple angry wild Gyarados by himself.
Interference on their PokéGear reveals the source to be a red Gyarados in the center of the swarm. Silver captures it, thus stopping the rest from rampaging. But it's only a matter of seconds before the two boys begin arguing again.
Suddenly, a fog covers the area. Gold instantly recognizes it as that of The Mask Of Ice. Secretly setting up a ring of razor-sharp icicles around them, the two boys fight along side eac other, before the Mask's taunting gets the better of Silver. Chasing after him alone, Silver calls upon all of the wild Gyarados in the Lake (as the red Gyarados is the leader of them) and uses their combined strength to attack the Mask.
Meanwhile, Gold is busy dealing with some of the Mask's Pokémon by himself. After cleverly defeating them, he hurries after Silver, only to find the entire lake frozen solid. Silver and his Gyarados are knocked out. Gold runs to him, only to see a giant chunk of ice smash into Silver, throwing him into the water. Claiming that Silver was being punished, he then attacks Gold as well. The last few panels show Gold and his Aipom the instant before a giant chunk of ice is about to hit them, and the impact. Silver's hat and PokéGear are seen tossed into the air.
