Bouncy Boss Robot

Hopping Egg Vulcan (ホッピング・エッグバルカン) is the third boss encountered in Sonic Chaos in Sleeping Egg Zone.

The machine is piloted by a robotic copy of Dr. Robotnik, which bounces around the arena, firing projectiles in the general direction of Sonic and Tails. Like previous bosses, the head is the only vulnerable area and can only be attacked once the machine is in jumping range.
