Well... I have the bag of presents in inventory. Probably from Christmas 2018, although I don't know which location.
2018 - Susan's Home - Diggy had to search the woods for Rudolph's bag of presents and bring it back to the Susan's living room.
2018? - There is a Challenge Mine where the elf at the Toy Emporhea sends Diggy off with a bag of presents to deliver to three people.
In either case, these items will probably be removed when the event ends.
