Love, Weather, Streanth:
Plant a veggie and go to the forest near the carpenter's house, with your veggie. Go on the little bridge and find the round pond, there throw the veggie in the pond and press A. A green lady will come out and grant you a wish. If you select 'Love', you will marry someone by the end of the year. If you select 'Steranth' you will get a power nut. If you select 'Weather' it will rain all year.

Blue Apple:
Throw three fish back in the pond across from the river and you will be given a blue apple to stay healthy so you can work through the night.

Rainbow Apple:
Throw 5 fish in the pond as fast as you can and all your red apples will change to rainbow apples. They make your 'life' and everything else infinite.
