Santa Claus

Santa Claus is a character in the Halloween Town world of Kingdom Hearts II. He is the leader of Christmas Town, and is constantly asked questions about Christmas by Jack Skellington. Jack Skellington almost always mispronounces Santa's name as Sandy Claws, leaving Sora and company in a state of confusion.

''Known to some as Father Christmas, Santa Claus makes children's dreams come true every year on December 25th, delivering presents in a sleigh drawn by flying reindeer. To get ready for Christmas, he depends on his list of this year's good little girls and boys.''

''It seems our friend Jack Skellington is a bit confused. He thinks Santa's name is actually Sandy Claws.''

Story
During Sora's first visit to Halloween Town, he is kidnapped by Oogie Boogie at Maleficent's request. Maleficent plans on turning Santa Claus into a Heartless. When Santa is captured, Sally saves Santa from Oogie Boogie. When Sora defeats Oogie Boogie, Santa tells Jack that he should concentrate on Halloween, and Santa should concentrate on Christmas. He also tells Sora to believe that he will meet Riku again.

During Sora's second visit, Santa's presents get stolen by Dr. Finkelstein's Experiment. He helps Jack make decoy presents to attract the Experiment. Jack and company get them back by hiding in a decoy present. After they defeat the Experiment, Santa Claus decides to give Jack a taste of what it's like to deliver Christmas presents. After Jack finishes delivering presents, Santa takes back his sleigh and brings forth beautiful snow drops as a present to those in Halloween Town.

Trivia

 * Santa Claus reveals that Sora, at the age of seven, told everyone that he didn't believed in Santa anymore, so, he is not on his Good Boys list, much to Sora's dismay. However, Santa Claus also reveals that it was another boy (Riku) who told him that.
 * Santa's advice that Sora should believe that he would find Riku is an echo of what happens in the third visit to Traverse Town in Kingdom Hearts, where Goofy tells Sora to believe that he would find Kairi.
