As with Emerald Hill, the first attempt at recording was successful, so it's probably obvious I've gone into the zone without a real plan of action (as the derp near the end of the video showcases) - but turns out I didn't really need one, as one attempt is all that's required for this Zone. While I did take the easier route in Act 2, the others don't offer that much in the way of resistance either, so I went with the path many don't even know exists, I certainly didn't until recently!
Something I forgot to mention in the video: The boss is actually a bit of a threat if playing as both Sonic & Tails, as Tails is a major liability during the fight, seeing how he causes the boss to be rendered invulnerable like Sonic, it's easy to pass through him and into your doom. That's probably why the boss has a bit of a reputation as a difficult fight, although I can't say I've ever thought of him as one of the harder fights, mostly due to how simple the strategy against him is to pull off.
