A few more ideas:
Fight:
Kiwi monsters
Grape monsters
Pine apple monsters
Banana monsters
Everything they drop can be used. With the Grapes you can easily make Grape Juices if you have a blender. For low level characters Grape Juice is a good pot to have around.
All other fruits can be compounded. If you get your characters the alchemy skill, they can happily compound the fruit (latania's, little gooseberry's and such) into fruits that can be used for the juices. More HP/SP with a small investment. This can also give you a nice amount of money!
Good luck on making and keeping lots of gold :)
