In the Poptropica island "Mythology," a drachma is a Greek currency that can be used to purchase items or unlock paths within the game. Players can collect drachma coins by completing tasks or defeating enemies throughout the island.
In Mythology Island, the coin you receive is needed to buy an item from a character in the game. This item is essential for progressing through the island's storyline and completing certain tasks. Make sure to hold onto the coin until you reach the specific point where you need to use it.
