I just had the weather machine e-mail and this is what I picked up:
  • 2 common bugs
  • 2 uncommon twigs
  • 1 rare coin


Right after that, I used some bottled rain and got:
  • 3 common bugs
  • 2 common coins
  • 1 common twig


As jeresandy said, I don't believe it matters as sometimes I'll get absolutely nothing and others I'll luck out. That's the whole point of something being rare I guess ^^
