Excuse me if it has been posted before,but i read a lot of topics and don't remember seeing these two things mentioned.
1)After completing Q24 talk to Faruk.He is happy and he gives you 2000 to show his support.(only 2000?Some prince he is!)I had Melusine and she got insulted and competitive.So,to show how much more superior and rich she is,she gives you another 2100!
.I don't know,maybe because by that time in the game you already have a decent amount of money(even before the Horizon island),i considered it pretty stingy of them.
2)After Q28 talk to the giant again.He opens the present and doesn't like the stupid skull,so he gives it to you.It's a Kahukulu!
