It's all random. I barely post and have been getting those jack-o-loots in my inventory. Candy seems to be extremely slow for me all of a sudden, though.

You can check your inventory by clicking the "Avatar" tab and then the "Usable" tab to the far right corner. If you don't have any, that tab will not show up.
If you do, you'll see the Jack'O'Loot (or whatever it's called, I keep forgetting) and you click on it and Open it to see what item you get randomly.
