Samhain

Samhain' (/ˈsɑːwɪn, ˈsaʊɪn/; Irish: [ˈsˠəuɪnʲ]) is a Gaelic festival marking the end of the harvest season and the beginning of winter or the "darker half" of the year. Traditionally, it is celebrated from 31 October to 1 November, as the Celtic day began and ended at sunset.

Empath: The Luckiest Smurf stories
In the EMPATH: The Luckiest Smurf story series, Duncan McSmurf would usually tell stories about the McSmurf tribal Samhain celebrations on Spook-A-Smurf Eve to his fellow Smurfs and to the Smurflings. Tapper, who does not like to participate in anything related to celebrating darkness, refuses to listen to any of those stories.
