The Panic Puppet Zone boss is the seventh (and penultimate if all of the Chaos Emeralds are collected) boss encountered in Sonic 3D Blast in Panic Puppet Zone, piloted by Dr. Robotnik. It contains three floors against a multipurpose arm weapon.
Robotnik's machine has three phases in three different arenas. Each phase requires three hits before defeat.
In the first phase, he'll use mace weapons at the ends of the arms. The arms will try to hover directly above Sonic and once within range, an alarm will go off to signify Robotnik's attempt at crushing the Hedgehog with his hovering arm. When not within range however, the arms center themselves straight and balls are fired from the shoulder areas instead. The solution to defeating the first phase is to lure the arms into a crushing attempt and quickly escape being crushed which will then leave the pounding arm momentarily disabled. At this point, the blue-lighted shoulder area will be vulnerable to attack for a brief amount of time.
The second phase contains hedgehog-seeking flamethrower arms, the same used in the Volcano Valley Zone boss. After each flame has been shot, the shoulder area will begin to glow, leaving it temporarily open to attack.
The final phase involves a series of ice projectiles, which ricochet around the walls. The best chance of not getting hit is to stay in the corners behind the ice-shooting arms, as the projectiles don't bounce into that direction. Like the second phase, a blue-lighted shoulder area will begin to glow after each projectile firing, signifying when to attack it.
- Unlike the first two phases, the third phase does not contain a Window shield surrounding Robotnik.
