Story : Gennai urges the group to travel to Server in order to defeat another enemy, informing them about Crests, which will allow their Digimon to Digivolve even further. While traveling on the ocean, the DigiDestined are swallowed up by Whamon, who is under the control of a Black Gear. Tai frees him with his Digivice, and as gratitude, Whamon takes the DigiDestined into an undersea store where the Crest tags are located. They fall under attack to Drimogimon and free him from a Black Gear. After recovering the tags, Whamon proceeds to take them to Server.
