Doosh are the rivals of Smoosh and the primary antagonists of the Insane Quest. Lead by evil deity Segami, Doosh appears to be bent on creating as much mayem and chaos in The Universe as possible, and are the ones responsible for killing Nico's former pack members. Doosh consists of the evil dopplegangers of the Smoosh members.


Recent members such as Sarah and Rustynuts do not have counterparts yet, as Smoosh has not encountered Doosh after Chapter III, while these new members were introduced after Chapter IV.
