I got to say, flushed! Along with some others, this has got to be my favorite episode! The alligator isn't really a villain, but I liked the change in environment in this episode. At a party, one of the attendees decides to go for a swim in the pool alone but she never makes it out, implying something ate her while swimming. And so, the next day Ethan is in the middle of a shower when the water stops running, leading him to go to school with half washed hair. Later in class Ethan and Benny are trying to cook pasta but there’s no water flowing through the pipes. When they look under the sink, they see a slimy green creature crawling through the destroyed pipe. Both of the boy's find out because Benny flushed one of his potions down the toilet, Rory also flushed two alligators. I think this was a great episode and is definitely worth rewatching!
