Shugalge use their corrosive poison to attack ships carrying berries between regions. They make these stolen berries into a very healthy Berry Juice, to help other aquatic Pokémon recover from poaching and oil spills.
Their poison is strong enough to eat through the hull of a tanker, and they spit it indiscriminately at anything that enters their territory. A Shugalge hides under rocks, keeping its body concealed inside its shell while eating stored berries.
