Sea Slugs, previously known as Molluscs or Waders, are enemies found in the Beach Gate. Sea Slugs, like many enemies, don't actively pursue The Hero. Instead, they will constantly walk in a single direction until they come into contact with something preventing them from moving further in that direction (such as a wall, another enemy or the player). If they come across a ledge or a cliff they will simply walk off of it, sometimes to their death.
Thanks to their pool-floats, Sea Slugs can move both on land and in water and are one of the few enemies able to do so. They are generally only seen where water is accessible and will normally end up in a pool of water.
Sea Slugs are tall and tan humanoid creatures with two antennae. They have a constant frowning face and wear a purple and yellow inflatable pool tube around their waist, much like Baki and their scarves.
