Answer: Diamond Mine
The correct answer to this question is Diamond Mine, where all the seven dwarfs work in the classic movie Snow White. Interestingly, the idea of seven dwarfs was not originally part of the Snow White fairy tale, but was added by the Disney animators. The names of the dwarfs - Doc, Grumpy, Happy, Sleepy, Bashful, Sneezy, and Dopey - have become iconic and are recognized worldwide. The popularity of the dwarfs even led to the creation of a spin-off TV series called The 7D, which aired on Disney Junior from 2014 to 2016.
