The First Boss of Sonic Arcadia, Giga Eggrobo! The boss arena is similar to the GHZ Boss, with two floating platforms appear at either side of the arena, then Giga Eggrobo falls from the sky, he jumps around (causing earthquakes that will freeze the player and cause debris to fall from the sky) and tries to grab Sonic, while also shooting pellets from his gun. When he reaches breaking point, he does a big jump, and the floor falls apart to reveal spikes, he then uses his cannon, Hill Top style, to burn the platform, you have to jump on the cannon to the other side. This boss takes eight hits.
