You do need to be normal in order to acquire a TF. The first TF you get can be cured with the plant found in the northernmost clearing of the middle section of the woods.
People have already found most of the Tfs so you can look at the discussion thread to see their findings: https://tfgames.site/phpbb3/viewtopic.php?t=17432
I will post a full list in a few days once people have had a chance to explore everything themselves.
