Were do you get different fruits from on animal crossing wild world?

you get it from friends or you send your native fruit to your villages and they will give you rare fruit.

for me, i occasionally go down to the beach and check the shore. sometimes, coconuts will wash up and you can pick them up and plant them, but you have to be careful with coconuts. they will only mature if they are planted close to the shore. And here's a tip, if you want a tree to grow to it's full size (aka mature) then use your axe to chop down a mature tree and plant it in it's place. Planting something in a spot where an already mature plant was guarantees that it will mature to full size!
