EGG-HVC-001

Bobbin Walker (EGG-HVC-D01) is the first boss encountered in Sonic CD in Palmtree Panic, piloted by Dr. Robotnik.

The machine is Robotnik's Eggmobile attached to a bipedal mech that contains two bouncy Bobbins on the arms (hence, the name), along with spikes on the foot area. Unlike the standard bosses from previous Sonic titles, however, the boss does not require a total of eight hits, instead only requiring three.

Robotnik will walk back and forth across the arena (although not to the end of the screen to the player's safety), occasionally stopping to charge an attack by moving the arms backwards, and thrusting them forward. This is the best opportunity to attack.

The color appearance of the boss varies between the Good Future and the Bad Future. In the Bad Future, the mech is a red and drab-gray color, while in the Good Future it appears as a pink and steel-blue-colored machine.

Trivia

 * In a beta screenshot of the game in the 1993 issue of Electronic Gaming Monthly, the Bobbin Walker was meant to have dual claws on the ends of the arms.
