SS, it's a hanukkah toy for children. I don't know to much about them except it's a game, kids spin the Dreidel, sing the Dreidel song. Kids play for chocolate coins wrapped in foil.
It's a wonderful custom, I love how you used the theme, Dreidel on her back and coins on her sides. and the colours are awesome as well. Great job!
Oh, and I love her eyes, very nice anime expression to them.
