To me, and presumably other parents in NA and the EU, a Windi is a small plastic tube device that you insert into the rectum of a baby to relieve gas pressure: https://frida.com/products/windi

Is that an intentional homage?

We were gifted a butt whistle (and a whole Frida set, which was great), and fortunately never got the opportunity to use it.
