Good Items in the Beginning of the game

If you're near the start of the game then this can really help you get some good items.

First, catch a Zigzagoon. Its special ability is 'pickup' so when it's in your party it can pick up items when you're walking around.

I caught one in the grass by Little Root Town and in less than an hour I got 2 ultra balls, 3 revives, 2 super potions, some berries and a few other items.

If thats not enough, then you get a whole team of Zigzagoon in your party and they will pickup loads of items.
