THANKZ ALL IF YOUR WONDERIN MOST OF THE HARVEST MOON GAMES ROCK ESPECIALLY THIS ONE

ANY ONE

Kappa is by the winter lake.You can get the blue power berry by dropping two cucumbers in the lake for the first day.Then drop 1 cucumber in the lake for 10 days and then he will give you the blue power berry.

In order to break the big rock you have to charge it and hit it.You have to do that for a couple fo times.

And you can only see the kappa in the spring, fall, and summer. And after you get the power bery, he won't give you anything else.

You may just fish him when you are fishing there, he will pop up and start doing a dance!?!?! I haven't yet but I hope to!

Actully kongboy you need the cursed/blessed hammer.

ya, you can find the cursed/blessed hammer on level 50 of the lake mine!!! but you can only find 1 truffle back there in the fall, and thats it, the truffle will sell for 500 dollars and you only get one a day!
