Trainers who want to make Spikes TM090 or Electric Terrain TM136 in Pokemon Scarlet and Violet will need a resource known as Pincurchin Spines obtained from the Electric-type Sea Urchin Pokémon — Pincurchin. As you might expect, this electric-type pocket monster lives exclusively on the ocean beaches of Paldea, as according to lore its primary food source is seaweed. They are quite timid and will not actively pursue any trainer who wanders into their comfort zone. However, it won’t retreat from a fight if threatened, and it has decent stats in Atk, Def, SpAtk, and SpDef. Nevertheless, its inferior speed means that countering combatants with ranged moves can make quick work of this Sea Urchin Pokémon.
To trap Pincurchin in Pokemon Scarlet and Violet, Trainers can search several locations near the sea on the Paldea region map. These locations include the northwest coast of Mount Glaseado, the beaches near Porto Marinada, the coast of the Pokécenter in the Southern Province (Area Five), and the coastline at the metropolis of Levincia. Wherever there is sand by the sea in Paldea, players are likely to encounter a Wild Pincurchin.
Finding Pincurchin in Pokémon Scarlet and Violet
Game 8 recommends that trainers find and capture Pincurchin i Pokemon Scarlet and Violet as early as possible in their playthrough. The reason is that there is an NPC in Levincia that players can trade their Pincurchin with for a Haunter. Those familiar with the ghost and poison-type Haunter will know that it can evolve into one of the best endgame and even postgame combatants, Gengar. This evolution is done by trading the Haunter with another player who owns both versions of the game. Of course, that doesn’t mean Pincurchin can’t be useful in combat, but in terms of countering other Flying or Steel-type opponents, there are many better alternatives.
It is possible to insta-catch Pincurchin with a certain type of Poké Ball in it Pokemon Scarlet and Violet, but those trying to weaken it first before capture are advised to use Ground-type attacks. As an Electric-type Sea Urchin Pokémon, ground moves are its primary weakness. As mentioned above, the Pincurchin has a chance to drop Pincurchin Spines when captured or defeated in battle. Spikes TM is a good way to deal massive damage to enemies passively, while Electric Terrain TM is an excellent buff that prevents one’s combatants from sleeping while also buffing Electric-type moves. Therefore, electric terrain can be a huge advantage in specific trainer matches or Tera Raid matches where sleep is a danger, or electric type movesets are optimal in Pokemon Scarlet and Violet.
