Find a copy of CB!'s monster catching guide She went into great detail about the simurgh.

Or as a paraphrase, just stay in the end towards where the temple is and go around in circles. Or stay 'in the sunny spots' if it makes you feel better.

my trouble right now is the regular tonberries-_- got all the master tonberries, and I have all the simurghs, (and I'd have just about all of them inside sin if I hadn't managed to reset my game after about four geminis (two of each) and those stupid turtles. And inside sin is so boring to go through so yeah:/)
