"Named after the iconic Halloween party song, this mesmerizing brew also makes for a spectacular punch. For bubbly fizz and more bite, stick with the lemon-lime soda. For more sweetness, use lemonade instead."
1½ ounces vodka
½ ounce blue Curacao
½ ounce grenadine (or 2 drops red food coloring for less sweetness)
4 ounces lemon-lime soda
Whether a cocktail or a punch, mix the vodka, Curacao, and grenadine (or food coloring) first, then pour in the soda or lemonade to taste. Pour over ice-filled glasses. For the punch, make a floating ice ring and throw in a few ping-pong ball eyeballs.
