Big Squeeze

Big Squeeze  is the seventh boss of Sonic Mania. The battle begins at the end of Flying Battery Zone Act 1 when Dr. Eggman drops the player into a trash heap.

Boss guide
The battle begins once the player is dropped into a pit of discarded robots by Dr. Eggman. The battle is against the electromagnet on the ceiling, which attracts pieces of the broken robots and turns them into functional Badniks. The strategy is to use the makeshift Badniks it creates to gain enough altitude to hit the electromagnet.

Each time one of the Badniks is destroyed, the walls of the garbage pit will close slightly, decreasing the amount of available space and eventually crushing the characters if the boss is not defeated quickly enough. With less space, however, the player gets more room to hit the electromagnet. Once it is hit six times, the player has beaten the mini-boss.

Trivia

 * One of the Badniks seen in the trash heap is Splats, a Badnik that was planned to appear in Sonic the Hedgehog.
 * However, Splats makes its official appearance in Sonic Mania in Press Garden Zone, the level after Flying Battery Zone.
