Synopsis
Searching for a new Digi-Egg Mega Seadramon traps the kids under an oil platform under the sea. Forced to secure the area to stop the area from flooding, they have a small air supply. The kids choose Cody to go for help in an emergency pod, knowing he needed to face his fear of water. Cody goes get Joe in the real world but has to lie to get him out of class. Meanwhile in the oil platform, the other kids find the Digi-Egg of Reliability and tells Cody to take it when comes to the rescue. Cody hesitates because he doesn’t think he is reliable. But Joe explains to him why he is. He takes it and Armadilliomon armor digivolves to Subarimon and with Ikkakumon, they defeat Mega Seadramon.
