Gastropod

Gastropod is a hardmode enemy that appears in The Hallow at night. This yellow, snail-like enemy flies about while hidden inside its pink shell resembling a balloon or Chinese lantern, only emerging to shoot pink lasers at the player. The lasers fired by the Gastropod travel very quickly and can be difficult to dodge, especially since Gastropods can target the player from a good distance off-screen before they can even be seen. Striking the Gastropod while it is preparing its laser will cause it to retreat back into its shell and not shoot the charging shot. Gastropods' range makes them difficult to run past and ignore without taking a fair amount of damage while doing so.

Due to the high amount of life and defense, high tier weapons are advised to defeat it.

Rare chance to spawn outside The Hallow on hardmode.

Trivia

 * In real life, gastropods are a class of mollusk that includes snails and slugs. The word "gastropod" is derived from ancient Greek meaning "stomach-foot," which these animals are so named because they appear to crawl on their stomachs.
