How do you get drachma in poptropica mythology?

I only know one way you can earn a Drachma.

It is by cleaning some graffiti off the wall of Hades.

You don't need 9 Drachmas. After you get further in the game, Athena will tell you to go ask Hercules again.This is after Zeus takes your items, Hercules won't move but then you tell him about the mirror Aphrodite gave you and then Hercules comes with you. You travel to the Underworld, Hercules will move the big rock in front of Hades's Palace and Hades will give you his Crown. Then you travel to Poseidon in the Underwater world, Hercules jumps onto this rock and it falls you go into Poseidon's Palace and He will give you his Trident. You go to Mount Olympus and You'll see a snake Hercules grabs it but it was actually Medusa, Medusa turns Hercules into stone but Hercules doesn't mind because he always wanted a statue of him on Mount Olympus. There is this man he sells bags containing wind for one Drachma you give to him and use it you will fly up near Mount Olympus but you will still have to climb up further once you are in Zeus's Palace you light the candles near his throne and you will have to deafeat him using Poseidon's Trident and Hades's Crown. You need to collect the Pink Clouds or then you won't be able to fly and you will lose. HTH (Hope this Helps) :)
