Catching Gastrodon in Cobblemon

Gastrodon has a catch rate of 75, which is moderate by Cobblemon standards. Bring its HP as low as you can without knocking it out, ideally with False Swipe, then apply sleep or paralysis before throwing. Those two things matter far more than which ball you use.

Where it appears depends on biome, time of day and weather. Our spawn biome guide explains how to steer the spawn pool toward what you are hunting.

Shiny odds are the same for every species, roughly 1 in 8,192 per spawn, so hunting a shiny Gastrodon is purely a volume game. See shiny hunting.
