Mix the softened peanut butter and powdered sugar together.

Spread evenly in the pretzels, setting them on wax paper.

Put the pretzels (on the wax paper) in the freezer for 15 minutes.  While they are setting, melt the candy melts following the instructions on the bag.

Take two pretzels at a time out of the freezer and dip them in the chocolate.  Note: mine were cute on the front and a mess on the back, but delicious all around.  If you want them to look more perfect, you may want to do a second dipping in the orange melts once the first layer sets.

While the orange is still wet, place a sunflower seed at the top of each one for the stem.

If you wish, once the orange is dry, melt some chocolate, and put it in a zip loc bag, cutting a teenie tiny corner off the end.  Pipe on a little pumpkiny face.  Now cackle at the pumpkin as you devour him.
