Shiranēyo (シラネーヨ) is an ancient AA dinosaur-like character that will only answer with “Shiranēyo” (シラネーヨ, lit. “I don't know”) and ends sentences with '–yo' (ーヨ). The female is called Shiranaiwa (シラナイワ), and their offspring are called Chiranēyo (チラネーヨ).

The original character, Shiraneyo, was created on 2channel's /kao/ board on June 13, 2000 by a user known as “Cat_Acid”.¹⁾ The user has since changed their name, becoming a Vocaloid producer named “Sakots” (サ骨) or “Redcard-P” (レッドカードP) with 800+ credited songs.

Despite its dinosaur-like appearance, their species is an egg-born mammal with remarkable abilities (e.g. enhanced speed, fire breath, regeneration, etc.). Unlike Zonu, they are gentle, mountable creatures. Their meat is considered a delicacy, which has led to the species being overexploited in the past. By the way, the 'space-adjustment dots' on their necks are moles.

Kuuki Yometenēyo (クウキヨメテネーヨ) is a Shiraneyo variant that presumably emerged when it became popular to provoke people by saying 'read the air' (空気読め, kuuki yome), normally translated as 'read the room'. It is said by a ghost, whose form was refined by AA craftsmen like “TEMPTER”, but the artwork itself is quite big and, ironically, it might've felt too disruptive to actually use as a result.

In the Western internet, the VIPsaurus is a variant which was edited to have a long neck and multiple spikes, befitting its dinosaur-like appearance. The character, most likely, emerged at Sageru on October 9, 2007.²⁾ Details aside, the character is quite abrasive, replying to the questions that they demand with a witty comment, and shouts “NEXT!” so the thread can move onto the next one.

• For the AA-themed Flash animations that remember Shiraneyo, the character often has a minor role.
