How to get the blueroot since it seems hitting the golem with spells doesn't seem to work: If you use the cat form potion the golem won't attack you, although it seems spells does not affect it. When close enough to one of the blueroots return to human form and dig it up. And don't forget to drink the potion of speed. Run to the next root and dig it up as well. Now just run past the golem and head back to the fire :)

You can also get money (at least in the mobile version) by watching videos (earn 400 coins each watch). You'll find the button in your profile view (it's under general). Good luck!

If you play on mobile then there should be a backpack symbol in the left corner at the bottom. Press there and you should have your profile and settings, inventory and more. Hope you already found it though :)

I don't know what part you're at but if it's the first time you're looking for her then she should be in her cabin in the swamp (go inside the mountain to get there). If it's where you need to talk to her about Puff then go to the boat outside the arena and she should be at the end of the boatride... takes a while to get there in the boat but she'll still be there.
