Pumpkin Twoheads, more commonly known as Ariados (though this name incorrectly associates them more closely with a species they are less-related to) were a species of cobweb spider closely related to the Twohead, the Ariados, and to a lesser extent the Happy-faced Spider. It was endemic to the Johto region. It was discovered only briefly in 1999, and evidence of its existence was revealed in 2018. It is now considered to be extinct, possibly out-competed by the much more successful Ariados.
When a Pumpkin Twohead is born it is know as a Spinarak. These juveniles are nearly impossible to differentiate from those of true Ariadoses, though their young seem to have a penchant for coloration usually associated with "shiny" Spinaraks.
Similar to Ariados, Twoheads have lost one pair of legs which never develop in the egg and do not grow in during any of its moults. The same has happened with six of their pairs of eyes, and as such they only rely on their primary base of eyes. Facial markings on the back of the body make it appear that they have a second set of eyes, but these are false and presumably meant to deter predators.
Upon reaching maturity, the juvenile's singular horn splits into two and their fangs give way to pedipalps. The abdomen markings become more dreadful and perhaps even somewhat pleated in appearance, resembling a jack-o-lantern.
