Divinity: Original Sin Enhanced Edition

We go to the witch's hut in the forest of Luculla. There is a barrier and mushrooms that can remove it, but you need to solve the riddles.
To the right of the dome we find a large talking mushroom Ikari. Mushroom knows everything about the White Witch, but for his knowledge he asks you to guess three riddles:
1. A hungry beast tore off my pistachio dress, tore out my silky hair by the roots, took away my children and fed me to the pigs. Who am I? Answer: Corn on the cob .
2. I cannot lie, I cannot lie, I can only lie. Who am I? Answer: Stone.
3. The length of my neck is twice the width of a toad's tail, the number of my eyes is half the number of seasons, and in the far east I cause hurricanes if I fly two minutes late! Who am I? Answer: Butterfly .

For correct answers, the mushroom gives a Maradino scroll, which will remove this barrier when read. Remove the barrier and the trophy is yours.
