Query: Ben 10

My nephew's reaction was priceless. He was so happy he started screaming, running around and finally ran up to me for a hug. When I let go of him, he looked up at me and whispered thank you and wiped the tears from his eyes. He had no idea that this toy existed he only thought that the cartoon character had it. Now he has one too.
