Conveyor Belt is the fifteenth level in both Meet Swampy and Swampy's Story.
Walkthrough
First, remove the dirt blocking the poison so it can get onto the red moving platforms (that act as vertical conveyor belts). When the platforms with poison reach the time, the poison will slide off, clear the algae, and drain to the side. Once the algae has been cleared and the poison has been drained, make a path to Swampy's shower pipe so the flowing water can get there via the red platforms.
