So your villagers will give you hints of what they want - usually 2 over the course of the month, a color hint and an item hint (red, brown, doll, wallpaper, etc) Keep track of these! Also, over the month the Able sisters will be selling the Santa stuff. Santa hat, beard, shirt, pants and boots i think. Buy all pieces.
On toy day (Dec 24th/Christmas eve) at 6pm Jingle will appear in your town and he'll be like "what if someone dressed like santa delivered the gifts?!" boom change into your santa outfit. Jingle will be like woah awesome heres a magic bag of stuff, pass it out.
In the bag (which you carry like a tool) will be the same number of presents as you have villagers. Each one will match a villagers described wish. When you give jingle back his empty bag, he gives you a present. if you got them all right, he sends his picture christmas day.
Thank you so much you guys! That really helped! I hope my villagers repeat their wishes again, though. xD I haven't been making note of them! Oops lol Thanks
