A little girl outside Houston got the surprise of her life: an American Girl doll.

Many children would love one of the expensive dolls, but this one is special.

Emma Bennett has a prosthetic leg, and with the help of a prosthetics company, now her doll has one too, WFAA reported.

Emma's parents bought the doll and had it shipped to a New York company called A Step Ahead Prosthetics. The company doesn't usually make prosthetic limbs for dolls, but this time it made a small version of Emma's leg, in pink.

A note that came with the doll said: "After a few weeks of training, she is ready to go home and lead a life without limitations with you."

In a video, Emma hugs her doll, crying and telling her parents, "Thank you for making a doll like me."

Since it was posted this week, Emma's video has had more than 6 million views on Facebook.
