Wanting a pony is very typical for little kids, yet not every one of them can have a pony, especially those that live in urban and suburban areas. Therefore, when a young, five year old girl named Mia Monzidelis asked for a pony and received no as an answer, she refused to give up on her dream and instead started up a business that sold big, interactive toy ponies. The business is called Power Pony and in addition to the pony toys, there is also an interactive iOS app. The toy ponies (and unicorns!) could even travel around any area while the child using it was in the saddle, riding it. Her father also helped her with this idea by exploring other toy ponies with her until they got an idea of what they wanted to do.
