Gastrodon
#231 in the Sword and Shield Pokédex • Sea Slug Pokémon
Sword
Its search for food sometimes leads it onto land, where it leaves behind a sticky trail of slime as it passes through.
Shield
The softness of its body helps disperse the force of impacts, so although its body is uncommonly squishy, it’s also surprisingly resilient.
