Alligators are popping up in everyone's toilets. Ty and Abby believe that the culprit is a man named T.P. Skinner, who is selling special toilets that get rid of alligators, and Ty and Abby suspect that he put the alligators in the sewers so he can sell his product. What the team doesn't know is that the alligators are a decoy for a much bigger plan made by their old arch-enemy, Lance Boil.
