...Take one down, pass it around
Find an area where you catch fairies, fish, fire, bugs, anything. Before you catch the item you swung at, hit start and put another C button item in place of the bottle. Now, the item you selected will be replaced by a bottle filled with what ever you swung at!!! WARNING: DON'T SAVE!!! If you do, you will lose items forever!!! Only save on the claim check, and the magic beans after you plant all 10, because those items are absolutely useless after being used.
