This face will haunt us this halloween...

Yeah for me they are almost everywhere at night. There's a tiny park nearby, and during the day it spawns around 6 pokemon, most of which are normal and flying types. But at night it can be anywhere between 4 and 6 Murkrows, and there's also the spawn in my kitchen, so that could make 7 murkrows spawned in one hour. When the Halloween event comes, that might get even worse: you put a lure or incense, and there's a murkrow most of the time.
They might be this years Gastly.
I get loads of Gastly where I live and last Halloween event they had increased its spawn rate, so they were everywhere. I got like 1000 Gastly candies during the event.
I really hated them after awhile.
I like the way Murkrow looks, but yeah, it's not fun catching them, so I'm slowly dreading this years event.
