When I look at the big box with a flask that has purple liquid I think EPF would do alchemy.
Alchemy means making potions with flasks and bottles.
Here are three things you can use for making potions: crushed roses, crushed milkweed and crushed dandelion.
Here a three basic potions: Red potion, Orange potion and yellow potion.
HERE are two advanced potions: shrinking potion and light potion.
I'm not sure if there is a purple potion?
Waddle on club penguin and try to find other kinds of potions and things to make potions!
