One of the oldest ways to trap a foe in the history of warfare – one which was used most famously in Kalos' Hundred Years War, but which has been used in countless other battles, against countless other unsuspecting generals – relies extensively on the Stunfisk. These flat pokemon struggle to win battles against powerful foes, but are extremely adept at burrowing into mud and paralyzing any creatures so unfortunate as to step on them. And while in a one-on-one situation, this is a mild irritant to any pokemon - except those few small enough for Stunfisk to devour - it is nothing short of deadly when deployed by a vast horde in the mud, with a whole army of ranged attacking pokemon to finish the job.
For this reason, tacticians and warlords in areas where Stunfisk are present have long been extremely cautious even in dirt battlefields, for there are many pokemon which can quickly bring fierce rains and turn dirt into mud. Although this trap can be equaled out with one's own Stunfisk corps, armies rarely have equally powerful ranged and charging attackers, so it can still give one side a significant advantage. Armies dependent on close quarter combat have often maneuvered into battles where Stunfisk can not so easily hide, and using the tactic successfully has always dependent on either the opponent being unaware that the Stunfisk tactic was possible (for these pokemon and associated strategies were new to the area, or the opposing forces were believed to lack access to Stunfisk or rain) or an exceptionally stupid foe.
Today, the decline of war has often seen Stunfisk mistaken for useless, but creative trainers in double and triple battles and criminal gangs defending against heroic trainers have hidden these pokemon to remarkably similar effect.
