Why are these things so hard to change

I finally get it together with the screwdriver and the batteries all on the floor I need them on WITH the toy - only to find out I don't need the screwdriver I need a coin. Really? A coin - it's been weeks (actually months, let's be honest) for me to make the effort and now I need a coin to put new batteries in the Talking Turtle?

So annoying! Does this ever happen to you?
