I think probably the first pony was so successful that Walgreens ordered another one.
I bet these have been selling like hotcakes. I think nearly everyone probably knows a nurse (or is one!). I for one, used to be a BSN, and both my sisters and my mother are/were nurses, so of course I bought a pile for them, plus a couple more for my sister's kids, so they wouldn't feel left out. Yes, they think I'm a bit crazy.
I am not particularly impressed with this new variation, but the pony IS cute, and of course for the above mentioned reasons, I do find all nurse ponies to be irresistible, so no doubt she will find her way into my house as well (although I won't be buying ponies for the mom and sisters this time)
Also- if they continue to sell nurse ponies at Walgreens with minor variations, I probably will want all of them. (Although I DO wish heartily they'd change the color of the plastic or hair!)
