Instruction Manual Description

Sonic Team Commentary (from Sonic Jam Strategy Guide)
| “ | At first this stage was set to appear about after Zone 10. Although there would be fewer Acts this time, we thought having about 18 zones would be good, but having each zone stand out and fit in the story in a way that was easy to follow, in the end it dropped down to 11 zones, and Chemical Plant was placed as the second stage. In the end it was a success (laughs). | „ |
Enemies
- Grabber - Spider enemy, hangs from the ceiling and grabs Sonic. Then unless Tails can destroy the Grabber, it explodes and hurts/kills Sonic.
- Lander - Anemone enemy, moves very slowly and spits out missiles.
