Thank you. But now, I am stuck again after entering the cave. There is a stairs that go down, it is revealed after crashing a rock among other rocks. The stairs is activated by another mushroom-thing. After going down the stairs, there are 3 moving mushroom-looking things. I can throw flames at them via the pole with flames. I suppose it has something to do with the electrified (or whatever those yellow thing is) gate. But I really don't know what to do now.
