how do I get further in the forest
To get further in the forest, you have to talk to the fairy queen about the giant plant blocking the way( encounter it first and escape, go to fairy queen and talk). She will tell you about the situation with the giant plants and send a fairy out to show you how to get through them. (Bonus: if you do the action of naturalizing the giant plants multiple times and talk to the fairy who helped, you get some new dialog). I hope this helps you and your journey Linglogg, and please ask if you have any other questions.
