"I did this with my 8.5 yr old granddaughter. We had a wonderful time watching “Roxy” develop. We both worked on this 50/50. It is not for someone who isn’t a “puzzler”. We had a few missteps where we had to redo part of the build. It is very challenging but so rewarding. While similar to legos it is very different in that you have to “lock down” each piece. She was so proud of herself when we finished. I will be purchasing another pet! Love them. Ours came out perfectly."
