Egg Press

The Egg Press is the second boss in Sonic Advance, which takes place in Secret Base Zone. Eggman is on a machine with a giant spring attached below, similar to the Bouncy Boss Robot of Sonic Chaos' Sleeping Egg Zone. While Eggman tries to jump over the player, eight hits (or six if in easy mode) must be inflicted on the machine to destroy it. Sometimes he will jump very high and fall, making an earthquake, which will inflict damage on the player, unless the player jumps right when the boss hits the ground.
