Happy Yam Ween Ruby Gloom : Season 1 Episode 12

The big holiday Yam Ween is upon the gang and things aren't going so well. Ruby has a lot of stuff to prepare for the holiday, while Skull boy tries to show everyone the true meaning of Yam Ween, but nobody will listen to him. Also, when the gang pulls names out of a hat to decide who to give a gift to, Poe's name isn't drawn and he feels a bit left out. (From: http://rubygloom.wikia.com/)
