I just got a shipping confirmation for the jigglypuff I bought during that brief window at target's website yesterday. So it appears they did have them and are not cancelling them!
I got mine too. Crazy thing is for some reason I was charged for and they are shipping two. I never checked my order confirmation. I must have had one in my cart already on my work PC when I kept getting the empty cart message and it kept it in there when I ordered on my phone. Completely missed it in the rush.
