After finding the Stick, I've been trying off and on for a week now to get the last remaining item in Crystal, and I haven't seen a damn thing. Averaging a Chansey encounter ever 600 or 700 steps and yet to find one with Lucky Egg, yet to come across a shiny Hoppip or Pidgeotto in the meantime, yet to do anything but drag my ass back and forth through the grass.

I honestly don't know what they were thinking by even including it, it's a ridiculous hunt.
