PREHEAT oven to 200° F. Lightly grease and flour baking sheets.
BEAT egg whites, salt and cream of tartar in small mixer bowl until soft peaks form. Gradually add Nesquik, sugar and vanilla extract; beat until stiff peaks form and mixture is glossy. Spoon meringue into gallon-size heavy plastic bag, then cut a 1/4-inch wide opening at the tip.
PLACE sticks about 6 inches apart on prepared baking sheets. Pipe meringue onto baking sheets into ghostly shapes about 1/4- to 1/2-inch thick, 3- to 4-inches wide and 4- to 6-inches long. To make eyes, lightly press morsels into meringues.
BAKE for 1 hour, 15 minutes or until meringues are firm to the touch. Turn oven off. Allow meringues to cool in oven for 1 hour. Remove from oven. Slide spatula under meringues to release. Store at room temperature in airtight container for up to 3 days.
