"Christmas Tree" is the first Christmas-themed episode of Teletubbies that debuted on BBC on December 22, 1997.
The Teletubbies listen to a voice trumpet saying "Christmas is a coming" and watch as some children select a Christmas tree and decorate it. Then the Teletubbies learn about Christmas when a Christmas tree magically appears in Teletubbyland. And four presents appear on the tree, one for each Teletubby. Now the Teletubbies have their own Christmas presents and were very happy.
