Yivo is a sentient, extraterrestrial being from another universe who communicated with universe "gamma" through the time hole called "the anomaly" made in The Beast with a Billion Backs. Shkle makes Philip J. Fry I the pope of a new religion, whose adherents are encouraged to "love the tentacle". Yivo used shkler "gentacles" (as proclaimed by Turanga Leela) to have sex with every living being in the gamma universe except Leela, unbeknownst to them. And is shown to be sometimes saying mean things to humans.
