Egg Frog

Egg Frog is the seventh boss on Sonic Advance 2. It is the boss for Egg Utopia and is controlled by Dr. Eggman.

Appearance
Egg Frog's appearance actually looks more like a spider of some sort. It is mostly gray, with yello headlights, orange parts on its legs, and dark-gray feet. An Egg Mobile takes up most of its body.

Battle
This battle is about gravity. As Egg Frog uses its legs to jump the ceiling to the floor and vice versa. When he does, he leaves behind a flame trail, forcing the character to leap to the opposite path or face certain death. Jumping high enough will automatically flip the gravity in your favor, so use this to hit the Eggmobile while flipping gravity.

Trivia
