can i destroy a tree?... because i dont want its' fruit...

No, once you have planted the seeds you can't destroy them. Next time around, don't plant any seeds it's not a must.

i have 3 banana!

That's OK, I had three mango trees. They all produce the same amount of fruit. The villagers don't seam to mind, as long as it's food.

Instead of planting the 2nd & 3rd seed that falls, I wait to be sure of getting all 3 different seeds.

how many different seeds are there?

I think the mango trees are prety In one village, I'm going for all mango trees. The banana is ok when it has fruit on it. What is the other tree though?

Papaya.

i would actually rather have 3 banana trees because they would not hide the collectibles as much as the mango
