If you have a vision camera you can use a pinata card to scan and generate an egg that contains a Wildcard pinata.
FourheadsIf there isnt enough space for your game to scan it the best way is to copy the image, open an image editing program (such as paint) make a large white background and paste the image into the centre. Then turn the focus on the camera all the way anti-clockwise.
Tip that worked for me, if the game cant see it turn the focus clockwise a tiny bit at a time until it does.
Tried and tested, can be scanned in and sent away for the records without any crashes.
