ISO: 2007 Jumbo Pinkie Pie (Australian exclusive?)

I have recently restarted collecting G3 ponies and as Pinkie Pie was my childhood favorite, she is the bulk of my collection. I finally got my hands on a 25th anniversary 20” long Pinkie plush for a good price and now I have my heart set on finding her jumbo sister! It seems like very few of these 3’ (90cm) babies are still around and even less so for Pinkie specifically. I am aware that the cost would be higher than many other collectables from the era and I’m willing to discuss a reasonable offer!

Please help me find this crown jewel for my collection!
