Sea-Sick and Tired

It seems the group has finally reached its limit after the Dark Masters' overwhelming ambush, and they are soon tempted into a trap set by one of MetalSeadramon's flunkies.

Synopsis
The group is forced to watch as the Dark Masters' arena explodes with Piximon inside as they escape in the forcefield he created. They then find themselves on a familiar beach they visited at the beginning of their adventure. Everyone seems to be quite down about both the loss of their friend and the fact that they haven’t really made much progress if they are on the same beach they started on. While trying to figure out if their whole journey has been pointless or not they hear someone yelling for help in the water. T.K. and Kari are eager to help the creature so all the kids take a rowing boat to where the splashing's coming from. The drowning Digimon turns out to be Shellmon, very likely the same one they fought on their first day in the Digital World. The Digimon manage to beat Shellmon in their Rookie forms, showing the team that they've become a lot stronger. Tai remembers that Agumon had to be at the Champion level to defeat the evil Digimon last time. Though everyone seems to be doubtful Tai wants to believe that their partners are stronger, and everyone agrees after explaining that getting stronger is what Piximon wanted for them.

The fog on the beach suddenly clears and the now completely worn out group heads for a snack bar nearby. While rushing to the stand Joe and Mimi trip and aren’t able to enter the shack. This turns out to be a good thing though because the snack shack was actually a trap set by Scorpiomon, one of MetalSeadramon's henchmen. He attacked them, covering them in sand which caused them to pass out. Luckily, because Joe, Mimi and their Digimon avoid the trap, they are able to sneak up on MetalSeadramon talking with Scorpiomon. MetalSeadramon notices that two children are missing inside the snack bar and orders his henchman to find them.

Scorpiomon chases after the remaining DigiDestined and their partners, but they easily outrun him because he ate a load of clams. He retreats into the water and when he reappears Togemon and Ikkakumon are ready to take him on. He's finally defeated when he gets distracted by some more clams, allowing the Champion level Digimon to digivolve to their Ultimate forms. Tai and the others start to regain consciousness inside the building. Mimi, Joe and their partners enter the building and have to wake up everyone to ensure that they safely escape. MetalSeadramon begins to burn the shack, thinking the DigiDestined are inside when it turns out the only occupant of the building was a knocked out Scorpiomon who catches fire and is punished by his master.

While in safety Joe doubts Tai’s claims that their partners are getting stronger, because it took two Ultimate level Digimon just to take on one of the Dark Masters’ flunkies. MetalSeadramon approaches the children on the beach and they are forced to escape into the water nearby. Lillymon attempts to fight him off to no avail. While the group is safely situated on Zudomon, MegaSeadramon disappears into the water then attacks, knocking them into the water and then causes Zudomon to De-Digivolve to Gomamon. The group is now powerless, and the Dark Master prepares to finish them off.
