Grumpy The Time Traveller
We’ve realized why Grumpy is so grumpy. He’s a time traveler from the future, and is bitter over the fact that he ended up back in the 14th century after having experienced a far more advanced and modern world.
How else can they explain him owning and playing a piano? That’s clearly a souvenir he brought back with him from the 17th century – when the piano was invented.
Kidding aside, but if Disney insisted on having Snow White be set in the 14th century, they should have made sure major details were historically accurate.
