Instructions
Play the game and follow the main story missions until you receive a quest to go to Login Mountain. Only then will you be able to access the world map.
Walk to Shine Terminal in Sunshine City and stand on the blue square to the left of the room. Press the "A" button to bring up the world map then highlight Chip Forest in the middle of the island and press "A" again to instantly travel there.
Follow the path leading left until you reach the dark part of the forest and you will randomly encounter Bearmon. Before each battle, Bearmon will be scanned and the percentage displayed at the bottom left of the screen. Each encounter adds 10 percent to the scan percentage, so after ten encounters the scan for Bearmon will be 100 percent.
Return to Sunshine City then go to your tamer house. Stand in front of the right computer and press "A." Select the "Digiconvert" option to see a list of all the Digimon you have encountered so far. The scan percentage displays next to each Digimon's name.
Scroll down to "Bearmon" and press "A." You will get a Bearmon and can then choose to add it to your party or send it to your farm island.
