Ingredients:

2 liters diet root beer 
24 gummy worms, plus more if desired 
1 pint low-fat vanilla frozen yogurt 
1 pint low-fat chocolate frozen yogurt

Preparation:

Arrange the gummy worms in a 12-compartment ice tray, letting them hang out over the edges of the tray. Fill with root beer and freeze at least four hours or overnight.

With a small ice cream scoop, fill the bottom of a one-gallon punch bowl with scoops of both frozen yogurts, using the full container of each. Very slowly fill the punch bowl with root beer, which will foam up to create the "slime."

Float the wormy ice cubes on top of the punch. Fill each punch cup with a scoop of ice cream and an ice cube. Float additional worms on top of the punch or in each glass.

Serves 12-15
