Check out the inventory info using the link at the bottom of ShebuyaCloth's entries which are usually in the first few entries of every event. I just looked and there are heaps of items that can drop...
Finally got the peacock yesterday and collected twice since - 2 gold nuggets, yay!
Now hoping I get the butterfly faerie. I don't really need more energy droppers but I won't say no to them.
55 gold nuggets seem a bit steep for such ordinary drops. I will definitely NOT be crafting 4. I already have heaps of items that can drop swords and armour, so very little incentive to get this Hart.
