Sorry if something is written wrong, I don't speak English.
I'm loving this game, but I'm stuck on the part where you get Glowshroom. If anyone could help me I would appreciate it, I even found the purified lake <3
You can find glowshroom in purified lake by random. Like when you enter to the purified lake, there a chance that you will get a glowshroom. I suggest you to re-entering it until you get one and bring it to plant at your house.
And your english is fine, no worry. English is not my first language too.
