Preheat oven to 375F. Nudge in muffin liners or mist muffin wells with cooking spray.
Whisk dry ingredients in a large bowl: flour, baking soda, cinnamon, pumpkin pie spice, nutmeg, sugar, and salt.
Combine wet ingredients in a medium bowl: oil, water, eggs, and pumpkin puree.
Fold wet ingredients into the dry ingredients until just combined. Place figs, chocolate chips, and walnuts in a food processor. Pulse for about 15 strokes (or you can always chop the ingredients). Stir in figs, chocolate chips, and walnuts. Fill 3/4 of each muffin liner with batter.
Bake for 20 minutes or until a toothpick inserted into the middle comes out dry.
