The idea behind the Pillow Pet is two-fold: First, that you want to have a stuffed animal with a vertical orientation. And second, that you do not want to use a stuffed animal for a pillow (because of its vertical orientation). Can you see the "stupid" part yet?
There is no reason on God's green Earth why you should have a convertible stuffed animal/pillow. All you're doing is cinching the stuffed animal in the middle. This product literally has no reason to exist. And yet, kids are going insane for it.
