Kenneth the Sewage Treatment Worker appears on Episode 99.9. Although he works at a Sewage Treatment Plant he often misspeaks and calls sewage ‘sewerage’. Although it is his job to treat sewage he does this in unexpected ways: taking it out to a Gold Class movie, to KFC, or a degustation meal at Vue de monde, taking it to the Green Lantern Ride at Movie World, buying it a Nintendo Switch or even projecting the movie ‘Problem Child 2’ or ‘Gremlins 2’ to it from the back of his Toyota HiLux. Thsi, of course, means that Kenneth doesn’t use usual methods such as cleaning agents and once tasting the ‘treated’ sewage decides that cleaning might be the way to go after all.
Kenneth has an uncle (also named ‘Kenneth’) described not as a regular uncle but a ‘kissin’ uncle'. The implications of this are unknown.
