Appearances in Christmas specials
Sonic Christmas Blast
In Sonic Christmas Blast, Sonic is first seen agreeing with Princess Sally that they will supposedly not get each other presents this year. He then tells his friend Tails that he and Sally made this same agreement last year, but while he had actually took it seriously last year, Sally had ended up giving him a bunch of presents anyway, and he felt bad about not getting anything for her. This year, however, he's now figured out that Sally actually does want to exchange gifts with him. However, things turn sour when they find out that Dr. Robotnik, in the role of "Robotnik Claus", is forcing the citizens of Robotropolis to give presents only to him. Sonic and Tails head to the North Pole and rescue Santa Claus. When Santa notices a funny-looking ring that Sally had given Sonic for Christmas last year, he recognizes it from a cave painting that says whoever wears that ring can achieve ultimate velocity by passing three tests of skill. Sonic successfully manages to pass the tests and achieve ultimate velocity. He then zips into Robotnik's fortress, grabs all the Christmas presents that Robotnik and his minions stole, and very quickly manages to bring them to everyone on Mobius, including Sally. Afterwards, Santa decides to retire and gives his job to Sonic.
Other Christmas productions
A year prior to Sonic Christmas Blast, a parody version of Sonic, voiced by Dan Castellaneta, made a cameo in The Simpsons episode "Marge Be Not Proud". When Bart Simpson contemplates stealing a copy of the video game Bonestorm, Sonic appears in Bart's imagination (alongside Mario, Luigi, and Donkey Kong), hyperactively telling him to go ahead and take it. Interestingly, this cameo would later be referenced in the Sonic the Hedgehog Level Pack for the video game Lego Dimensions, in that Sonic quotes his line from this scene if he is teamed up with Bart.
