Scavenger Hunt

THE ONE PIECE IS REALLLLLL!!!!!!
Hey guys, my buddy Eiichiro Oda just told me the location of the one piece. The bad news is he sent me these cryptic riddles , and I can't even rub two neurons together to figure it out. So it’s up to a group of 4 people to finally put this anime to rest. There's 10 riddles in total and no time limit , but do you have the hutzpah to traverse uncharted lands to become the PIRATE KING !!!! By the way, you don't need one piece knowledge to answer the riddles.
