Just make sure you go some south of the garden and talk to the guys standing there.
They'll talk about some cult or whatever and offer you a book.
Read it, learn it, strip naked, dance a jig, then go talk to the middle statue.
The third statue is just gone, doesn't matter, the middle guy is who you should talk to.
Kill the frogs later.
Also, KILL SPIDERMONKEYS, THEY ARE THE DEVIL'S WORK!!!
