The magestic ibex is widely regarded as the most argumentative and contrary animal in existence. There is no record of any human ever outdoing a full-grown ibex in any sort of argument, debate, disagreement, fracas, feud, vendetta, or war.
When the ibex detects speech, or any loud noise, it will respond with an appropriately well-thought out rebuttal.
Just talk at the app, and the ibex will talk back!
