ASTRA ZONE Sea Slug Railway Sea Slug Blue Sea Slug T-Shirt

Have you ever seen sea slugs connected together like a train underwater? Sea slugs are hermaphrodites, with the male's organs located at the front of their bodies and the female's at the back. When two of them are lined up together, it looks like they're playing train (though apparently, sometimes three or more are connected together). Sea Slug Train Umiden Sea Slug Train is a character based on a green sea slug.
