UPDATE: The key pictured below is (sadly) not mine. I had this link underneath it but somehow managed to delete it in the original post.
When I was a little girl I had one of these magical keys. It opened up a world of information about animals for me and for anyone standing nearby when I used it. I used to take this key to the Detroit Zoo and also to the (now closed) Children's Zoo on Belle Isle in Detroit, MI.
When you put the zoo key into one of these "talking storybooks" a voice would start telling you all about the animal that lived in the exhibit that the storybook was near. It was such fun and a great adventure to go through the zoo looking for the storybooks. As far as I can tell the Detroit Zoo no longer has them but I did discover that interactive Storybooks have returned to the San Francisco Zoo. The photo below is what one of the old Talking Storybooks looked like.
I used to watch a Saturday morning TV show called Bwana Don. Bwana Don taught us about animals and he had a chimp named Bongo Bailey on the show. There were also cartoons. I don't remember the specifics, but I got my elephant key from him....what a treat it was!
What ZOO memories do you have?
