Pumpkin Spice M&M's - another good one! Very vague pumpkin flavour with cinnamon and spices. Nice and chocolatey, this one is a milk chocolate one.
They have another Halloween flavour out, Candy Corn White Chocolate M&Ms, but I didn't try that one. It sounded a bit strange, even for someone like me who likes to try all the new stuff. If I change my mind I'll report back.
