Slice off the top of each mini pumpkin at a slight angle, just like you would for a jack-o-lantern lid. Use your spoon to scrape out all the seeds and stringy flesh until the inside walls feel smooth. Pat the cavity completely dry with paper towels so the fruit salad doesn't turn watery once it's added.
Dice the strawberries, pineapple, and apple into bite-sized pieces so every spoonful gets a mix of textures. Halve the grapes and peel the orange into clean segments, removing any white pith. Keep the blueberries whole since they add a nice pop of color against the orange pumpkin shell.
In a small bowl, whisk together the honey, lime juice, and pumpkin pie spice until fully combined. This light dressing is what ties the fall-flavored spice into the fresh fruit without overpowering it. A thirty-second whisk is really all it takes to get it silky.
Add the strawberries, grapes, pineapple, orange segments, blueberries, and apple into your mixing bowl. Pour the honey-lime dressing over the top and gently fold everything together with a spatula. Go slowly here so the softer fruits like strawberries don't get crushed.
Spoon the fruit mixture into your hollowed-out pumpkin shells, mounding it slightly above the rim for a fuller look. Slice the banana at this point and nestle the pieces on top so they stay fresh and don't brown early. This is also when the bowl starts looking genuinely picture-worthy.
Sprinkle the toasted pumpkin seeds and chopped mint over the top for crunch and color contrast. Pop the filled pumpkin bowl in the fridge for about 10 minutes so the flavors settle together. Serve it chilled for the best texture and the brightest fruit flavor.
