Chemical Plant Zone
From Sonic Retro
Chemical Plant Zone is the second zone in Sonic 2.
Instruction Manual Description
Flash through a high-tech maze bult with pipes and ducts. Robotnik's flooded the factory with a pool of toxic liquid called "Mega Mack" that poisons Sonic in a few moments!
Villains
Enemies
- Grabber - Spider enemy, hangs from the ceiling and grabs Sonic. Then unless Tails can destroy the Grabber, it explodes and hurts/kills Sonic.
- Spiny - Anemone enemy, moves very slowly and spits out missiles.
Boss
Boss: Dr. Robotnik's Chemical Machine Hits: 8 When he first appears, jump on him and hit him like there's no tomorrow. You can kill him before he finishes filling up his cup of chemical. Otherwise, he'll drop it on you. But honestly, you should have NO problem getting rid of him quickly. Watch out for the receding ledges on the sides, though.
Note: In the beta, sprites have been found of Robotnik dumping the chemicals in his machine on him. This may be a missing boss ending sequence similar to the one in Emerald Hill Zone.
