My Babysitter’s a Vampire - Season 2 Episode 4

This episode starts with Ethan singing in his shower, when the water cuts off. During one of his classes the next day, the faucet won't work, and while trying to figure out the problem, he spots a green, scaly thing in the ripped-in-half pipe. After coming across "it", Ethan and friends find out its history: the school was doing a "locker raid" and Benny had a potion he needed to get rid off, but before he could flush it, Rory rushes in, putting something in: baby alligators. Benny flushes them both done, and its at that moment that they realized the gators must have grown, mutated by Benny's potion. They see it captured on TV and thinks the problem is solved until Erica drops by with bad news: the one that attacked her was bigger. Another gator to deal with. Will they be able to find it and stop it before its too late?
