POKEMON RUBY ANY% GLITCHED: Rare Candy Manip
This manip was tested using the second gym trainer in Roxanne's gym, although it should work with any fight as long as you hit the correct frames.

It also assumes you have 3 pickup mons in your party. Having more would increase the frame windows for the pickups, so it can mostly be extrapolated if you want to mess with more Zigzagoons. Having less mons would decrease the frame windows.

Having non-Pickup mons in between the Pickup mons doesn't matter, the numbers just correspond to the 1st/2nd/3rd Pickup mon in your party.
