Bead WormMedia:SonicChaos GG US manual.pdf[1], known as Dangerous Ball Tower (デンジャラス・ボールタワー) in the Japanese manualMedia:Sonic Chaos Game Gear JP Manual.pdf[2], is the second boss of Sonic Chaos, fought at the end of Gigalopolis Zone.


The Bead Worm rises up in the beginning, sways back and forth, launches its segments at the player, and then replaces them to begin the cycle anew. The first and third segments are thrown diagonally into the air, bouncing off the ground, while the second segment is launched horizontally on the ground. Luckily, the head’s top is weak, and so the player can destroy the boss by jumping at it and landing squarely on the top of its head. It'll throw its bottom-most body segment in the air, so they must stay on the ground when attacking.

This boss reappears in Knuckles' Act 1 of Sonic Mania's Mirage Saloon Zone, as an exclusive mini-boss for the echidna.

4 segments variant bug

In the Master System version, it is possible to face this boss with 4 segments instead of the usual 3 segments. In the path to the boss, if the player takes the bottom corridor instead of the middle or top one, the boss will spawn with 4 segments instead of 3.
