The Bomb Fever can only be utilized during the Egg Dealer boss fight. It is activated by hitting three slots on the Egg Dealer that correspond with the Bomb Fever icon. When used, the Egg Dealer will drop explosive red spheres.
If the player is able to stop the third slot themselves, the Egg Dealer will trip and drop its bombs on itself, causing them to blow up and damage the Egg Dealer. If Eggman uses the ability, the Egg Dealer will continue moving around the arena while dropping bombs at the player.
