Directions: Carefully slice VitaTop in half lengthwise, so that you are left with 2 thin round Vita "slices." Set aside.
In a small bowl, combine all other ingredients. Stir until smooth. Spoon mixture into a small sealable plastic bag, and squeeze it down toward a bottom corner of the bag. Snip a tiny bit of that corner off with scissors, so that you have a makeshift piping bag for distributing the filling.
Lay the bottom slice of your Vita flat, with the cut side down. The exposed side will be the "face" of Mr. Puffy -- it is the smoothest, most beautiful surface to work on. Carefully draw a jack-o-lantern face on it with the pumpkin mixture: 2 solid triangles for eyes and a squiggly mouth. (See photo!) Set aside.
Lay the top slice of the Vita flat, with the cut side up. Squeeze ALL of the remaining pumpkin mixture (there will be A LOT!) evenly onto the exposed side. Gently place the other Vita slice -- with the "face" up -- on top, creating a sandwich with a pumpkin-mixture filling.
