Jacknix are equipped with two brains by mistake of nature. The brains' favorite pastime is to talk philosophy with themselves so a Jacknix can never be alone. Because of their two brains the Jacknix is not necessarily schizophrenic, however, it is more prone to mental absences than other life forms. Jacknix talk gladly with everyone about everything and afterwards find it genuinely great that they had a talk about it. Since one with two brains can play bongo drums really well it is clear that in almost each band a Jacknix can be found. Bands with several Jacknix are very rare however. The Beatlers,a band with 4 Jacknix has therefore a special popularity which goes so far that they are surrounded by younger girls who are constantly screaming at any time at any place. A special Jacknix is Muffie, who has four brains. Beside a larger portion of insanity he also received more intelligence.
