Pumpkin Basket

once equiped you can just collect the candies by clicking on them, instead of holding the "Use" key/button and waiting for the delay bar to fill), so is way faster, i used to collect about ~30 by holding "use"/"E" key, but with the pumpkin bucket i can easily collect +70.
in order to get one you can open a small loot bag.
TL;DR: collect as much candy as you can on first event trigger, then upgrade candies to small loot bag, and open some untill you get the pumpkin bucket, then on the next event trigger (about once each two in-game days), just equipt it on your itemsbar, and run arround clicking candies for more than 2x times the speed.
Pro-Tip: when you collect a candy, the direction you are looking at will be where a new candy will spawn, so you can go around collectiong them aiming at a central point, then collecting them looking at same spot, then forward and back. for extra speed.
