To make Crawling Hands: heat oven to 400 degrees. Line two baking sheets with parchment paper. Whisk egg yolks and 2 drops red icing color in a small cup until blended; set aside.
Roll out one sheet of puff pastry dough on a lightly floured surface. Using cutter, cut out 6 hands. Placed on prepared baking sheet. Using a small paintbrush, paint egg yolk onto tips of fingers to resemble fingernails.
Bake pastry 15 minutes or until golden. Remove to wire rack to cool. Repeat with remaining sheet of puff pastry dough.
To make chicken potpie: melt butter in large saucepan over medium heat. Whisk in flour; cook, whisking, until bubbling. Gradually whisk in chicken broth. Stir over medium-high heat until mixture comes to a rapid boil and thickens. Stir in remaining ingredients. Return to a simmer; cook for 4 minutes or until vegetables are tender. Pour mixture into serving bowls and garnish with Crawling Hands.
