"Ikkakumon's Harpoon Torpedo"

Matt and Tai got into a big fight and Joe tried to break it up, only to end up as part of the arguement.  Tai wanted to climb Spiral Mountain to see if there was anyone nearby that could help them.  Matt thought the trip itself was dangerous.  That night, Joe decided to climb the mountain...on his own.  Gomamon came with him, and it was a good thing, too, becuase they were both attackd by Unimon, a horselike digimon.  Luckily, Gomamon digivolved into Ikkkakumon and, with Birdramon and Greymon's help beat Unimon, and destroyed the black gear.  Unfortunbately, when they finally reached their destinatioon, there wasn't much to see.
