Bests & Worsts Reviews from Amazon

We bought this product as a gift for my nephew. The product arrive earlier than expected which is great. When it first arrive, the zipper is broken. The Creeper foot area doesn't look like the picture at all. It is small and the checker box prints are cut off on the side and they are hanging on top of the foot instead of at the bottom. My son happen to have the same backpack that we bought a year ago from ThinkGeek and after comparing them, they are similar yet different. Here's the pictures of where I found differences. Left one is the picture of the backpack for my nephew. Pict 1 : The backpack seems to be smaller Pict 2: The green color tone is different, my son's backpack has more than 1 green color tone Pict 3: The foot of the backpack is much smaller on my nephew's Pict 4: If I look at the foot bottom, it's all scrunch up and not square Pict 5. Further look inside the backpack, I notice my nephew backpack is missing an extra cushion that is supposed to be inside the foot (pict 6 and Pict 7) As far as I know there's only one version of Minecraft Backpack out there. Are there many different one?
