Add 1 cup hot water to Jell-O and stir until dissolved. Add in cold water and mix well.

Pour enough Jell-O to fill the jar half full. Place the remaining Jell-O and Jar in the refrigerator to set.

Once set, using a toothpick, press gummy candy down into the Mason jar.

Fill the Mason jar a quarter way full with whipped cream and add remaining Jell-O to fill the jar.

Add in more gummies pressing them into the Jell-O with the toothpick.

Garnish with more whipped cream and body parts. Add a few drizzles of red gel frosting to give it a more "bloody" look.

Keep refrigerated until ready to serve.
