Ah, the beanstones...
As the ancient civilization was very short, you'll need a short Mario to be able to find them. However, it is perhaps a bit tricky...
Both my friend and I found 9 of the beanstones, but could ever find the last one. Determined to get them all, I later made a map, but had no trouble in locating all ten. Perhaps the 10th beanstone hides itself unless you find out where it is before digging up the 9th... or something.
If you still can't find them all, you can use the
funny litle map I made. It's got grid lines, but they don't mean anything. It's also not to any set scale.
But, if you can read it, go for it.
...Perhaps.
Go Moon!
