The animated intro for Sonic Mania was such a hit with fans that a batch of short cartoons was released, collectively known as Sonic Mania Adventures. The fifth episode seemingly concluded the spin-off story, but it turns out SEGA had one more chapter up its sleeve. Embedded above, the sixth episode has a decidedly Christmassy theme.

These cartoons are all a bit twee, but they're pretty amusing nonetheless, and well worth a watch if you're a fan of the blue blur. What do you think of Sonic Mania Adventures, and its surprise Christmas episode? Try not to get too spiky in the comments below.
