I found an envelope in my mailbox today. It had some some weird looking symbol where the sender's address should have been, but I decided to open it anyway.
We've been watching you. Since you enjoy puzzles, we've taken the liberty of offering you one. If you check your Google Drive, you'll notice a new file we've added for you. Enjoy.
Questioning how they would be able to add a file to my drive, I open it up and sure enough, there is a new file. It's named halloween.zip and has some numbered folders and images that appear to be puzzle pieces.
Can you help figure out what the image they sent me is?
EDIT
For those that don't want to download the zip, the images are below. Each row is from a different folder named 1 through 15. There is also a 0 folder that contains a single txt file with the text
Nothing to see here... Move along, Move along.
