Zashi is a Ninja Prisoner NPC in Brig Rock. Zashi, Hashi, Mashi, and Steve were traveling through Gnarled Forest and fighting Stromling Admirals when they were caught by Captain Jack Knife and his Pirates. Angered that there were Ninjas in his jungle, Captain Knife had them locked up in Brig Rock. However, Captain Knife did acknowledge that he did learn from the four Ninjas that the best way to beat a Stromling Admiral was to wait for it to sink its anchor before attacking it from the side.
