Role in the film———————————————————————
After the news about the toy noise, Grandsanta was seen watching on the news with his old pet reindeer and Arthur interrupted him. After Malcolm's celebration, Grandsanta and Steve had conflict to decide who will be Santa and played a game. Grandsanta decided to help Arthur on the mission to get Gwen’s present to her before the sun came up. Grandsanta and Arthur had gone the wrong way through Toronto and Bryony, the wrapping elf, was discovered to be a stowaway in the sleigh, and, had another idea to get one more reindeer which was a sign from a dealership and Arthur distracted the owner with a gun and escaped. While they were traveling, Grandsanta and Arthur encountered lions in Africa, and Arthur put the hungry lions to sleep by using his slippers and singing “Silent Night“. The antiquated communication device on the sleigh woke up and disturbed the lions, so they got back in the sleigh and flew off. Arthur and Grandsanta rescued one of the reindeer from the lions using magic dust. When Grandsanta and Arthur were riding on the sleigh, Steve told Arthur on the HOHO about their father’s retirement and planned to have his job. Arthur and Grandsanta landed on the beach and Arthur felt hopeless and gave up, but, Grandsanta reminded him that he was like him. After Arthur read the note about Gwen, Arthur and Grandsanta used the boat to get to Trelew, England in the ocean (which is where Gwen lives), about three thousand miles away. Arthur and Grandsanta were waiting for the sleigh, and the reindeer came to save them just in time. Chief Silva and her men thought that they were aliens and used a plane to destroy the sleigh and Grandsanta faked his death. After they gave Gwen her bike, they had a happy ending.
