Pooh dressed as Santa Claus.
Santa Claus is a jolly old man who lives in the north pole and brings gifts to people at Christmas time. In Winnie the Pooh and Christmas Too, Pooh and his friends write letters for Santa Claus telling him about the gifts they'd like to receive. Unfortunately, Pooh forgets to send the letters and is not able to deliver them personally, for the north pole is too far away, so he decides to wear a white beard and a red suit and build improvised gifts for his friends. However, they soon realize that Pooh is not the real Santa. Still, on Christmas day, Pooh and the gang receive the gifts they had asked, meaning Santa somehow knew what they wanted after all.
Santa Claus appeared for the first time in the series in Pooh's Super Sleuth Christmas Movie, a film release for the series My Friends Tigger & Pooh. Darby and the other Super Sleuths visited the North Pole in order to return one of his reindeer trainees, Holly. Santa granted the characters' various Christmas wishes, including allowing Eeyore to join the team pulling his sleigh. In this special, Santa was voiced by Jeffrey Tambor.
