When the kids were little I got them a puzzle of poison dart frogs from Ravensburger. It would take time to describe it. The pieces were identical triangles with head or tail of the frog on each of the triangular sides. You had to match up heads/tails and complete the puzzle. Okay? The point is that it was a memorable puzzle. It’s gone. It’s not online or on Ebay. That great puzzle went where all stuff goes when you’re not looking. There was a time when all of my old clothes went into a bag in the closet. If I didn’t look for them in a year, the bag went to the Salvation Army. I was none the wiser. I just lament that some treasured stuff is missing. Gee, that was a great puzzle. Oh! Hey, I got to see some poison dart frogs up close and personal. Wow!
