For the filling: In a small saucepan, combine half of the water with the Sour Punch Bats. Cook over low heat, stirring occasionally, until the Bats have melted and the mixture is smooth. If you’re having trouble getting the candy to dissolve, use a spatula to press the candy against the bottom of the pot. If you still see clumps, strain the mixture through a fine mesh sieve before using. Set aside. Repeat with the Sour Punch Pumpkins.
Place the cream cheese and salt in a large mixing bowl or the bowl of a stand mixer. Beat the cream cheese with the paddle attachment until smooth and creamy (2-3 minutes). Scrape sides of bowl as needed. Turn mixer on low speed & slowly stream the sweetened condensed milk into bowl while mixing.
