Does anything about their appearance change when you pour hot/cold water on them? If so, then no, they didn't come with a Snow White
If they don't change then I can't help ya.
I had a set of dwarfs (I know the plural is dwarves but apparently in Snow White land it's "dwarfs"), that looked just like these as a kid. I can't remember most of the changes, but I'm pretty sure Sleepy's eyes change so that he looks like his eyelids are closed and he's sleeping. And Bashful gets pink cheeks. And Doc's gem changes colors.
