I'm currently at 149/150 for Watefront of getting the Purple Pumpkins about 10 hours after starting. Primary issue being that on my One X I've had to manually check every corner, light post, car spawner, balcony, sign and planter with my eyes as I run through because the laughing they are supposed to do isn't happening for 90% of them and I've only had the sparkle effects show on maybe a dozen in here. One of them I found after I re-logged because it was high up over a road I had driven through about 10 times and only saw because it was giving off purple sparkles. My last one is somewhere in Prentiss but I don't think I'm going to find it if I need to find a dark ball that also rarely has it's bright face showing and it likes to look at the wall it's by.
