Old Reliable

An unwise attempt to stand up to the Digimon Emperor leaves Gomamon in a terrible state, but he manages to send out a distress signal, which is picked up by his old partner Joe, and the other DigiDestined.

Synopsis
After being abused by the Digimon Emperor as the Gizamon went under the Digimon Emperor's spell, Gomamon sends a alert to Joe. He and the other DigiDestined go to the DigiWorld, only to find Gomamon buried in the snow. They decide to destroy the Control Spire in the area so they build a sled out of trees so that they can cross the cold snow field to get to it. The Digimon Emperor realizes what they intend to do and sends Frigimon after them. They pass the Frigimon easily but Cody catches a cold after falling into the freezing water, and Joe stays with him while the others go after the Spire. Armidillomon comes along and Armor Digivolves to Digmon to fight an easy-to-beat Shellmon, but Ebidramon causes some trouble. While Digmon defended Cody, the others destroy the Spire. Gomamon Digivolves to Ikkakumon, frees Digmon and destroys Ebidramon. The DigiDestined return home with Gomamon's promise to protect the area.
