Digimon Adventure

Tai and Agumon land on a snow-covered island and are forced to defeat a Frigimon. After destroying the Black Gear that was controlling him, they cross over to the island where Matt and Gabumon landed. Meanwhile, Matt goes out to search for his brother against Gabumon's advice and gets hypothermia. Once the two boys meet up, they end up fighting each other until a Mojyamon attacks them. They defeat the Mojyamon and expel the Black Gear that was controlling him.
