Most important thing to note is that there is a collections ACH for the dolls called Misplaced Dollies. So make sure you get 2 of each dolly so you can also get the collections ACH.
This also applies to task 3, you need 2 of those dollies too, so get 2 of each item to combine. (Doll stuffing is not pre-lootable for task 3 but can be for the collection)
Do it with a druid. Dollies spawn incredibly fast. Campfire is nice too if avail.
