Time for another Sonic X Blog, and on to episode 4. In Chaos Emerald Chaos, a chaos emerald is found in a construction site, and Sonic and Robotnik both race to try and get it first.

As per usual, there are plenty of high-speed thrills to be found here, as well as some neat plot development. What's more, we're finally able to see Chris getting involved in the action, instead of just being a bystander. If you've been watching up to this point, you won't want to miss this.
