History
Yivo is one of the oldest beings in shklis universe. Since Yivo has no gender, the preferred pronouns are “shklee”, “shklim”, “shkler” and “shklis”. Shklee was lonely and wanted to find a soulmate. As Nudar and Bender abused time travel, a rift leading into shkler universe went open. Only organic beings can go through because of the matter destroying any robots. Fry met Yivo and was penetrated by shklim. Shklee had penetrated every being in the galaxy with shklis gentacles, with the exception of Leela. Leela figured out the truth of Yivo’s gentacles, disgusting Fry. Since Yivo is stuck in shklis universe, shklee is supposed to stay in there. If shklee goes to the universe of Earth, shklee would shkluffocate, leaving shklim breathless.
