Hehe, feeling miserable here too Haven't seen a Gold cowbell for like 3 months now

Since June 2016 I have done around 300 trucks deliveries and got a total of 20 Gold cowbells. I only can't seem to remember how I got my Brown Corgi Puppy pet. I didn't win one but I bought it with gems or Gold cowbells. And with over 7,500 screenshots can't find it quickly, lol.
So perhaps it was a total of 23 Gold cowbells.

And to get 2 cowbells with 1 truck, I think I've been lucky to get this only twices so far
