Napstablook is a ghost-monster who lives in the underground, the Ruins more specifically. He mostly likes to lay on the floor and pretend he’s trash, or race snails in a good game of thundersnail. Although he is in the ruins, he doesn’t live there. He lives in Waterfall. He doesn’t show emotion, and it’s not known if he even has emotions. He cries uncontrollably, but he doesn’t sniffle or even seem really sorrowful. He hates the nickname “Blooky”.
