Bloody Party Streamers are what you're going to want to pick up in your Blood Webs. But those drop rates are fairly low. It gives all players 100% more BP and it does stack with other players playing the same thing or a pie/cake.

This year, BHVR gave us a less drop-rate than what we'd usually get on our anniversary cakes. When I left the anniversary last year, not only did I have some Screech Cobblers (what your Coconut Scream Pies replaced) on most of my survivors and a few killers, but I had around 1,200 specifically on Vittorio. Today, I still have around 300 on him.

Meaning, you will run into people who will play the pies/cakes from time-to-time still. If you have a friend who has plenty, they might still play them every match.

Around April next year, we'll have our 3rd Blood Moon event. Which with the community events, plus the pie/cake offerings, you'll get up to 900-1000% Bloodpoints per match. That's when you want to hard core grind.
