Spider Mobile

The Spider Mobile is the eighth boss of Sonic Mania. The battle begins at the end of Flying Battery Zone Act 2, where Dr. Eggman enters the arena with a modified Egg Mobile which is shaped like a spider and has a protected cockpit. The boss has a large bumper on its abdomen.

Boss guide
The battle takes place on an elevator that seemingly rises endlessly. The Spider Mobile drops down on to the elevator and moves left and right, and occasionally generates electricity between its two pincers from which it will shoot three electric orbs at the player. The Spider Mobile's cockpit is immune to traditional attacks. Occasionally, there will be one of two obstacles on the sides of the elevator where the player can damage it: After eight hits, Eggman's Egg Mobile explodes, and he escapes using a jetpack. The elevator finally reaches to the top, leading a path straight to the Capsule. After releasing all Animals from the Capsule, the player advances to the next Zone.
 * A row of spikes on both sides: In order to damage the Spider Mobile here, the player must hit its bumper enough times so that it is propelled into one of the rows. Alternatively, the player can use the spindash to gain enough speed to hit the bumper a single time toward the spikes.
 * A row of spikes on one side and a spinning pole on the other: In order to damage the Spider Mobile here, the player can either hit its bumper enough times so that it is propelled into the spikes, or they can launch themselves off the pole and into the bumper to propel the Spider Mobile into the spikes.

Trivia

 * The Spider Mobile is one of three end of Zone bosses that cannot be hit by traditional means, the other two being the Mean Bean Machine and the Gachapandora.
 * The Spider Mobile resembles the Egg Tarantula from the Sonic the Hedgehog comic series.
