Holiday Island

Introduced in the season three episode "Depth Takes a Holiday". An alternate reality accessed through a portal in the back of the Good Time Chinese Restaurant where the holidays are manifested into live people who attend a high school called "Holiday Island High School". The holidays resemble the most common stereotypes or things associated with them. The biggest holidays, Christmas and Halloween, are the most popular students at the school, though Guy Fawkes Day is also a member of their clique. The high school is largely populated by nondescript students who are, according to Cupid (St. Valentine's Day) apparently, "A bunch of Saint's Days".
