Dungeons where Halloween crystals drop?

Only the boss in Maze dungeon (Deux Marble) summons Decayed Pumpkin when he dies, which can drop Halloween Crystal with cca 25% chance. Nothing happens in Horror Honeymoon or Dragons Nest. We appreciate new decoration, but we need that Decayed Pumpkin! Please, fix those dungeons, maybe introduce some new ones and surely compensate us with at least 20 crystals in mail (for every 100+ char). If it stays like this, there is no way anyone can collect total amount needed and we will again have event with rewards or goals impossible to reach...
