I remember trading over everything to Sapphire and sending over a ton of zigzagoon to do it the first time because I gave up trying to figure out how to make it work with the purified pokemon and I was gonna be trading most of them over for dex completion anyways, I think I may have switched to wingull at some point just because I was getting so sick of the zigzagoon. That trade animation is still seared into my mind over 15 years later.
