¡Ponte en Onda, Scooby-Doo! 1x14

The gang visits the town of Rockwellville in search of a Christmas mystery, but all they find is a pterodactyl who seems to have nothing to do with Christmas. Meanwhile, Daphne, who is tired of having her December 25th birthday overshadowed year after year, tries to convince the gang to celebrate her birthday instead of Christmas.
