However, there are a few things to note:
* Sonic Christmas-themed episodes: Several Sonic shows have episodes that feature Christmas themes or elements, though not full-fledged specials. For example, in "Sonic X," there's an episode titled "Merry Christmas, Shadow" where the heroes celebrate Christmas.
* Sonic Christmas-themed comics: There have been numerous Sonic comics featuring Christmas-themed stories, even some holiday one-shots.
* Fan-made content: Fans have created their own Sonic Christmas-themed content, like animations and stories.
So while a dedicated Christmas special hasn't been officially produced, there are definitely elements of Christmas sprinkled throughout the franchise!
