Under Pressure

Whamon shows up in the group's hour of need, giving them the time and rest they need to prepare for the upcoming battle against MetalSeadramon.

Synopsis
All hope seems lost for the kids, until Whamon shows up, ambushing MetalSeadramon and carrying them away. Minutes later, MetalSeadramon begins a search with a group of Divermon, while Whamon finds a distant island where the kids can rest. After everyone attempts to fish on the island, Gomamon hears of some nearby Divermon from a school of fish and they're soon on the run. Whamon escapes by swimming to an area of high pressure in the ocean where the Divermon cannot follow, but MetalSeadramon catches up. When Whamon surfaces near a coast, Agumon digivolves to WarGreymon in order to fight MetalSeadramon. While the other Digimon defend the kids, MetalSeadramon attemptes to crush WarGreymon in his jaws.
