Due to the nature of the video, I have to set it to "Made for kids".
The breakdown of the animation and the new rig will be in another video and you can comment there instead. The Sonic head rig is made with a new 12 position grid with custom scripts and will be discusssed in detail there.
Any serious inquiries, email me at anitomicals@gmail.com

Made with After Effects and the DUIK plug in
Music: Monkey watch, Rhythm Heaven Fever
