Sonic the Hedgehog 2/Chemical Plant Zone

A zone themed on a large industrial plant, producing the deadly Mega Muck compound (the strange pink water which can be noticed and in some cases must be negotiated through). The Boss of this zone is a goo shooter piloted by Robotnik. The platforms on the left and right keep disappearing. You will die if you fall down. Robotnik will suck up water in his machine and when full will aim the bucket at you. Robotnik is vulnerable while he is sucking up the water, however he does it over the disappearing platforms.
