Hello,
Unfortunately, we do not have this type of item available on our website but I bet the people at Cross Eyed Cricket can either tell where to purchase the tree that they used or they may even have it for sale through them? I didn't see it on their website but they did have a Contact Us option and I am sure you can just email them and ask :) Here is their website address: http://www.cecricket.com/index.htm
Hope this helps! Thank you.
