Winner of the Maryland Invent A Game Challenge, Sierra Bouthner wowed the judges again this year with yet another innovative idea. The 12-year-old's idea, the Dog Groomer, won her first place in the state of Maryland in the Invention Dimension Challenge. The Dog Groomer is an interactive dog grooming head made for dog lovers.

Here's what Sierra has to say about her idea:

"Along the line of the Barbie Styling Head, this is different heads of different types of dogs (example: chihuahua, pomeranian, poodle) in which you can groom and style. You can shampoo the fur, blow dry, cut the fur and of course add some bows! I feel it would be fun to play with because I am 12 years old, and I have a pomeranian and a cock-a-poo and I love dressing them up! This toy can come in a variety of little breeds of dogs that are so cute and allow anyone to have fun with them. You could even include voice activated doggy sounds! "

Sierra received a prize of a $500 JAKKS Pacific Prize Pack.
