The butt of many jokes, the rectum plays a serious role when it comes to pooping. This fecal loading dock is lined with nerve endings that, when filled with poop, tell the brain to find a bathroom pronto. Strong muscles push the poop out of the rectum and through the anus and, if you’re lucky, into the toilet! In case you're looking for your own to snuggle, our new plush rectum is now available for preorder.
