Is the film hatchy a true story?

I never heard of it. the closest might be Hatchy-Milatchy- full title Land of Hatchy Milatchy- pronounced exactly as it is spelled, which was a juvenile program in the sixties. Two Girls playing Guitars and telling stories in a magical and mystical park- that was evidentally the title designation. I have no idea where they got the name from. There is a Hetch Hetchy Dam in California.
