Corrected entry: In the beginning, the mirror instantly goes from green to black. It should have faded into black.
Corrected entry: When the animals are helping Snow White to clean the cottage, some birds bring big yellow flowers and put them in a blue vase on the table. When the dwarfs arrive and Bashful takes the flowers to smell, the flowers are completely different from those that the birds have brought and the vase is brownish and small.
Corrected entry: The dwarfs give their whole bedroom to Snow White, and they sleep downstairs. There would be seven beds and seven pillows upstairs, and there's one downstairs. So why did they fight over the one downstairs, instead of just going upstairs to get their own pillows? Snow White would also only need one, and even if they are too small, we can see the one downstairs is big enough.
Corrected entry: When Snow White goes into the "cute little cottage", the animals follow her (with the turtle at the end). When the dwarves come home, all the animals sleeping race back down the steps. (By the way, the turtle has finally gotten to the top of the stairs and has finished breathing a sigh of relief as he gets run over.) When the animals run down the stairs, they knock over the turtle, who hides in his shell to keep himself safe as he starts bouncing down the steps. Later, you can see the spot where he landed, but the turtle isn't there. Did the turtle leave? Probably. Where did he go? And besides, was he fast enough to get there, wherever "where" was?
Corrected entry: When the witch is reading the recipe for the poisoned apple, she reads "The sleeping death" twice, even though we later see that it's only printed on the book once.
