North

My little nephew, North, got two new puzzles. He will do them several times a day. He would pour both of them out on the table and keep them separate, do one of them, and then the other. They are made my the same company, so the pieces are interchangeable. He was away from the puzzles for a little while, so we mixed them up. When he came back, he was quite distraught.

North trying to figure out the what is wrong.

Examining the puzzles - a little confused.

Telling us his puzzles were not supposed to be like this.

After this incident, we did help him put them back the right way.
