The Missing Link

I bought a puzzle a while back and one day Tanya and I decided to make it.

We had our trouble times, and even found a piece on the floor. Oops!

When we were close to finishing is when it got hard.

Some of the pieces didn't seem to fit anywhere.

We had 3 pieces left, and 3 spots where they should fit. To our surprise, they didn't! They had the right shape, but they would not fit. I was upset. A perfectly new puzzle, and it wasn't complete!
