When walking along the shores of Galar, it is not unheard of to feel a sudden jolt in the foot – a jolt which, if not promptly treated, can give any trainer a taste of what their pokemon feels when paralyzed. One is advised to watch where they're going, lest they inadvertently step on a Pincurchin.
Pincurchin are not interested in human prey, which are too large and, even when stunned, often capable of fighting one off. They are ambush predators who feast on amphibious pokemon, and even purely aquatic ones who get washed too close to them at high tide, and if their spikes fail to kill them, a jolt of electricity in the water seldom fails to finish the job. (The seaweed they are so frequently seen eating is more of a digestive aid, for a Pincurchin's body is too simplistic to break down food alone.) Humans – and other living things of their size – the Pincurchin simply ignore, for their tiny mouths would struggle to devour any creature so big.
If only the puncture wounds they leave behind could be so easily forgotten! Humans, in the interest of avoiding painful and at times serious foot injuries, have tried to clear the beaches of these pokemon, but Pincurchin control efforts have been as difficult as those in Alola against the related Pyukumuku. With no better options, travelers near Galar's shores are advised to always pack Full Heals and ideally to not travel alone; if all else fails, the nurses at the Circhester City Pokemon Center are more than capable of treating Pincurchin wounds – if one can make it there.
