I found my first Golden Peach in Monster Rancher 1 with my most recent Monster, A Tiger/Tiger with 999 intelligence. I used that peach on him and now I absolutely cannot find another one. I've been looking in Reno in that round looking building on the western side of the map. After 20 or so tries I have yet to find another one. Can you only find one with a certain monster or do you have to wait a certain amount of years before they become available again?

I've seen a few people say they've found more than 1 peach with the same monster. Or are they dirty, dirty liars? ^_^ Any help would be vastly appreciated.

You can only find one peach per monster, unless it finds more than one on the same trip. The waiting a certain number of years thing is a myth.

You can feed a monster more than one, though.
