Ep 21. Under Pressure

Just when it looks like it is about over for the kids and their digimon, Whamon shows up to rescue them. Soon after their escape, the Divermon are sent out to look for them. While checking over his computer, Izzy discovers that WarGreymon has the ability to destroy Dramon type Digimon. The Divermon find the kids and attack Whamon, but when Whamon dives down quickly, the Divermon can't follow him because they can't handle the pressure change. Izzy uses his computer to find a tunnel that leads to a safe place...for a while that is. Soon MetalSeadramon finds them and Whamon rushes to the surface and ends up in a bay. When MetalSeadramon attacks, Agumon and WarGreymon WarpDigivolve and prepare for battle.
