halloween.zip file

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.

• hmmm, tempting, but as a programmer I know better than just open a strange unknown zip file ^^; – stack reader Oct 28 '16 at 15:03
• I opened it (AVG would tell me if its bad) and its fine – Beastly Gerbil Oct 28 '16 at 15:03
• @BeastlyGerbil I fear you may have an excessive amount of trust in your AV package... Admittedly, it would be a strange vector for attack, but there have been stranger ones... – Matthew Oct 28 '16 at 15:08
• @stackreader I was going to post the images, but 135 images is quite a bit. Plus I needed a way to split the pieces and also have the 0 folder. – David Starkey Oct 28 '16 at 15:19
• Still, posting links to not well defined files is heavily frowned upon on this site. -1 for me. Also, the tag "mechanical puzzle" doesn't go very well with a .zip file. (Would jigsaw-puzzle not be better?) If you're just aiming at putting a lot of images in a puzzle, alternatives are better - and an overview image in the puzzle would defenitely be welcomed. I've vote -1 on this question for the moment for these reasons, not actually juding the actual puzzle. – BmyGuest Oct 28 '16 at 16:40

If we put the pieces 1-15 (shown below) in a $4x4$ grid and slide using 'Nothing to see here' we get the The final image (sorry for putting it together badly) is:

File 0 has a text document which says:

Nothing to see here... Move along, Move along.

The rest are typical jigsaw puzzles.

The pieces in the file called 1 fit together like this:

Seems to be a pumpkin navel...

The pieces in the file called 2 fit together like this:

The pieces in the file called 3 fit together like this:

Clearly part of a pumpkin.

The pieces in the file called 4 fit together like this:

The pieces in the file called 5 fit together like this:

The pieces in the file called 6 fit together like this:

The pieces in the file called 7 fit together like this:

The pieces in the file called 8 fit together like this:

The pieces in the file called 9 fit together like this:

The pieces in the file called 10 fit together like this:

The pieces in the file called 11 fit together like this:

The pieces in the file called 12 fit together like this:

The pieces in the file called 13 fit together like this:

The pieces in the file called 14 fit together like this:

The pieces in the file called 15 fit together like this:

And all of these put together give us a pumpkin shown at the top!

• First picture looks like a naval (like on an orange), but the second picture more resembles a pumpkin (Halloween). – jstnthms Oct 28 '16 at 15:37
• @jstnthms just finished 3 which is clearly the bottom of a pumpkin – Beastly Gerbil Oct 28 '16 at 15:43
• For putting them together, it might be a slider-type puzzle where 1 goes in the top left then 16 is a blank square at the bottom right. The pieces that then get moved might have some sort of conversion to letters that match image 0? – Sconibulus Oct 28 '16 at 20:05
• @Sconibulus Ive just put them together and I don't think so – Beastly Gerbil Oct 28 '16 at 20:29
• @Sconibulus That was the idea, with the slider-puzzle resulting in the final image. BeastlyGerbil just kinda bypassed the sliding bit and put them in the final configuration. – David Starkey Oct 28 '16 at 20:57
