How to Get Soul Wood in Cozy Grove

Getting Soul Wood in Cozy Grove is essential to advancing through the game. It's the single most important resource in the game, allowing you to upgrade Flamey and reach higher fire levels. That, in turn, unlocks opportunities to meet new bear spirits, spread color around the island, and harvest more resources as a result of that spread.
How to Get Soul Wood in Cozy Grove
To get more Soul Wood, you'll need to complete quests — really more like little errands — for the bear spirits on the island. Each completed errand will earn you another log of Soul Wood that you can feed to Flamey. The more logs you feed him, the more he'll need to reach the next fire level.
The number of logs you can collect each day is hard-capped, but it varies day to day. In the first few days of play, you'll be able to rack up a sizable stack of logs for Flamey to consume, but from there supplies will taper off. Most days you'll be able to get at least one from each spirit on the island, but anything beyond that is out of your hands.
If you're ever unsure if there are still logs to collect, just talk to Flamey. He'll tell you how many more logs are waiting around the island that day.
This is part of Cozy Grove's larger ethos of taking things slowly and pacing oneself. It aims to be a short, meditative practice you can return to each day for a little bit of calm. To do that, it prevents you from flying too far on any individual day.
