Line a quarter baking sheet with parchment paper and set aside.
Put the peanut butter pumpkins and butter in a small bowl that sits comfortably over a small saucepan filled with a couple inches of water. Bring the water to a boil and whisk until melted and completely smooth. Add the chocolate nuggets and melt until completely smooth.
Spread the chocolate into an even layer onto a parchment lined baking sheet. Decoare with the chopped peanut butter cups, M&M's and fruit gummies and allow to set until firm in the refrigerator or freezer, about 35 minutes. Break into pieces and enjoy!
You can also melt the chocolate and butter in a microwave safe bowl in 30 second intervals stirring until smooth.
