Melissa and Doug Sound Puzzle

Anyone else have a Melissa and Doug Sound puzzle and it random get activated when light switches are turned off????

Seriously was going to bed and turn the switch and the dog barks at me!!!! I totally forgot about the puzzle and my heart skipped a beat.... Grrrrrrr

The puzzle did similar things at my parents but different animal would be activated.

Oh and it dies not do that when the pieces are in but E is over those puzzles so I guess I will be on edge until the puzzle is dug out of the toy box by R
