Reddit you're my only hope! Can someone help me find my mother's hat?

Yesterday my mother lost her hat while walking at Half Moon Bay. I know it doesn't sound like a big deal but she has been very dejected since. We bought the hat on a trip we took together about ten years ago to the San Diego Zoo and she loved the thing; she brought it everywhere and it had a great deal of sentimental value.

I've scoured the internet to see if I can find the same one anywhere but I can't seem to find anything even close.

Reddit you're my only hope! If anyone has this hat (couldn't even find a picture to help you out), or knows if where I can buy one( I'm told the San Diego Zoo no longer sells them) please let me know! If you have one that you no longer want I will gladly pay you for whatever you bought it for and the shipping!

Purple/Lavender in color with green text Ring shaped, with a hole in the middle where one's head would go. Somewhat unusual design, clips in the back Made out of a foam/felt like material, similar to a foam finger

Has anyone seen this hat?
