Robotnik unleashed the Egg Walker upon a Fabian Vane concert in the Casino Night Zone, where he panicked the crowds and caused some destruction, though his main target was Fabian himself. Having learned his lesson from previous encounters with Fabian and his singing during the war, he disabled the mech's audio receptors. However, Amy Rose was able to put a stop to the attack by firing a USB drive loaded with mp3s Fabian had recorded earlier into one of the sockets below the machine's screen. With Robotnik hindered by Fabian's terrible music playing directly into his brain, the robot was quickly disabled.
