What are those holes on the bottom left piece?
Can you attach more stuff to it or something?
every piece has at least one hole in it. i think you can choose which holes to punch out of the stickers, because they come in whole squares with numbers to show which sticker goes with each piece, so you have to peel out the stickers so they come out perfectly into the puzzle piece shapes and then punch out the holes in the sticker. i would imagine leaving them in would get annoying, so i punched all of them out. so there are a bunch of holes in the puzzle pieces.
the only thing that is in a hole is the town clock. from what i saw, every set had its own terrain, character, and bigger object, and two of them have something smaller that is put into a hole (like my town clock). the little piece of paper that showed each set and how to place the stickers on the puzzle pieces showed that one object that is wedged into a hole can be replaced with the other, or you could use them both.
probably the best part about these things are that they can all be put together. but i only got one.
