Description from site:
One of my favorite things about December is pulling out all of the old Christmas movies I loved as a child. It’s tradition! Every year, among many others, our Christmas movie list included Rudolph the Red-Nosed Reindeer. You remember -- the 1960s stop-motion version, complete with reindeer, Santa, an elf who wants to be a dentist (a dentist?), and my personal favorite, the abominable snowmonster.

These whimsical slippers are inspired by the abominable snowmonster, but sized for little feet, from baby to small child. They’re perfect for all the little monsters on your list!
