How do you get different fruits in animal crossing wild world?

Answer 1

Either you go to someone else's town and get their fruit, or your virtual Mom in the game will just give you the exotic fruit randomly in the mail one day.

OR

If you mail native fruit to other townsfolk (fruit your town has to begin with) they may send you exotic fruit back. BUT most of the time they will send furniture or something. And Coconut trees can be grown by planting a coconut (washes up on shore) near the beach.

Answer 2

You have to go to different peoples towns, and collect their fruit then plant it in your town for different fruit to grow.
