Its Needles can inflict more damage than a normal attack. However, it is not a really strong monster.
"Gatlinghog" is a portmanteau of "gatling gun" and "hedgehog." The Gatling gun is one of the best-known early rapid-fire weapons and a forerunner of the modern machine gun named after its inventor Richard Gatling. The Gatling gun's operation centered on a cyclic multi-barrel design which facilitated cooling and synchronized the firing/reloading sequence. Each barrel fired a single shot when it reached a certain point in the cycle, after which it ejected the spent cartridge, loaded a new round, and allowed the barrel to cool allowing higher rates of fire without the barrel overheating.
