I tried getting it once, but turns out you can only have 1 drachma.
You can't
You don't. You don't need the autograph and you can't get the nine drachmas.
Yes. It was called drachmas.
They used gold drachmas.
no you don't
The answer is you dont have to get nine drachmas you only could get one drachma
You clean the graffiti off Hades palace and then this guy gives you drachamas
There is one drachma. Get it from the guy in the underworld (Hades temple) for cleaning the graffiti.
There are many more than nine goddesses in Greek mythology. However, nine of them are:HeraAthenaArtemisDemeterPersephoneAphroditeEileithyiaHestiaIris
You don't. The only drachma on the island is the one earned for cleaning graffiti at the temple of Hades. It is used much later on the climb to Mount Olympus.*Except for talking to Hercules, nothing in Herc's Hero Hut has any function at all.
You don't need to get the 9 drachmas; he lowers the price and you have to do the other challenges first you must go to Olympus village where you must speak to Athena who will get Hercules to help you move the rock in front of Hades' throne room. :)
To get the money to give to Hercules in Poptropica's Mythology Island, you need to complete tasks for characters around the island to earn drachmas. This includes helping the villagers, completing challenges, and collecting items to trade for money. Keep exploring and interacting with characters to gather enough drachmas to give to Hercules.
