Fun game but...

I really enjoy this game, but one thing that is really bugging is that it is so darn hard to find certain chargers to complete a collection. On a few days, I have spent all of my energy trying to find the river pearl, and nothing! Please fix this to make it easier to find chargers...very frustrating!
