Noshishi, a brown anthropomorphic boar marked by a distinctive mole on his right cheek, serves as the younger twin brother of Ishishi. Both siblings sport green shorts, orange vests, and occasionally don green scarves paired with blue umbrellas. They act as loyal companions to Zorori, sharing his love for sweets and talent for mischief.

Their origins are briefly touched upon in a 1993 film, which references their childhood vow to avoid returning to their village until achieving success as villains—a narrative thread left unaddressed in later stories. Their names stem from the Japanese word *inoshishi* (wild boar).

Noshishi exhibits a knack for drawing, notably recreating a genie’s likeness from memory with precision. In *Secret of the Double Z*, he becomes entangled in a time-travel mishap triggered by an alarm clock device, which transports the group to the past. There, they cross paths with Zorori’s mother and collaborate with Zorondo Ron to reclaim their machine from authorities while evading a kaijuu.

Subsequent media does not expand on his personal history or evolution, leaving these aspects largely unexplored.
