Bakezori are another type of tsukumogami. When zori (thonged Japanese sandals) are neglected or mistreated, they can come to life and run around the house chanting "kararin, kororin, kankororin! (Eyes three, eyes three, and teeth two!)" This could be a reference to geta, another type of thonged, wooden sandal. The three eyes could represent the three holes drilled for the straps, and the two teeth could stand for the the two wooden blocks that make up the platform for the shoe.
Here's a picture of a real bakezori that got loose in the house.
Yokai Masterpiece #6 - Bakezori - thong sandal, mixed materials.
Bakezori usually have one eye, but this one has two eyes because I'm tired of seeing so many one-eyed obake. Plus it looks cuter with two eyes.
