Force Gems are crucial for restoring the Spirit Tracks, but many are optional and can be found by completing various tasks for NPCs or by exploring hidden areas. One significant source of Force Gems is the Rabbitland Rescue mini-game. Located in the Forest Realm, this mini-game challenges you to capture runaway rabbits scattered across the overworld. There are 50 rabbits in total, and each group of rabbits you return to the Rabbitland Rescue owner will reward you with a Force Gem. Collecting all 50 rabbits is a lengthy but rewarding endeavor, as it unlocks powerful train upgrades and other bonuses.
