Where is the garden of sphinx in mythology island poptropica?

That depends on what you are talking about. The statues of the gods and goddesses are in the museum. The statues of women that ask you " How can I inspire you today?" are in the same place you find the free reed pipes. The statues of Zeus are found in Zeus's palace but you can only see them when you go to the top of a special mountain to fight Zeus. Good Luck!
