- For other usages of "Labyrinth", see Labyrinth (disambiguation).
The castle corridors are filled with ghosts and guillotines, arrow-firing bird soldiers and treacherous traps. Watch your step on the narrow walkways - there are drops on each side, and it's a long way down.
— Description, Sonic Labyrinth
Labyrinth of the Castle is the fourth and final Zone of Sonic Labyrinth. Projectile-lobbing Badniks perch on inaccessible slabs of terrain and flaming arrows fly hither and thither across the long corridors. The boss of this zone is Smiley Bomb.
