Wait, nobody just calls these popsicles? (Central US, was a kid in the 90s) I loved all the flavors except the light yellow one which was banana sometimes depending on the brand.
When I was a kid we were all perfectly aware of the Popsicle brand, and we still called these things popsicles. Like how every tissue is a Kleenex, or every adhesive bandage is a Band-Aid.
It's still flavored liquid that's been frozen. The stick doesn't make a huge difference to a ten year old. In some ways this is better because it doesn't drip all over.
If Kleenex never made a tissue with infused lotion, or only with infused lotion, people would almost certainly still use the term for the other kind too.
In my mind a popsicle has a stick and anything thats in a tube like this is an otterpop, even though otterpop is a brand name and ain't nobody buying the real otterpops.
