Rise of the Horseman (Episode)

This episode begins exactly where it left off in the last episode (Ryan) where they see the kid infected with Horse-Itus. The kid then runs after Will, infecting him. This episode may also be episode so far with the most references to other shows/songs/etc.

Apparently the Plumber has seen a case of Horse-Itus before, hence the fact that he asks Ryan for the cure, although Ryan doesn't know. He leaves the T.O.I.L.E.T. and goes outside to find Will with his normal head replaced with a horse's head, and having a Western accent. Will then tells the Plumber that he likes his life a lot better as a horse.

Will runs away, while Plumber runs after him, but then decides to stop and think what the cure is for the common cold, the cause of a sick horse, and the cure for a sick horse. He comes to the conclusion that he needs a grass shake, so he later asks Ryan to build him a blender. The Plumber then starts collecting grass from other people's yards. The Plumber collects enough grass, later going out to look for Will.

Will then says to himself that he smells a smell. A smelly smell that smells smelly. (Which is a reference to the first Spongebob Episode) He then chases after Plumber, catching up to him and commanding him to watch him do the "Neigh Neigh". He then does the neigh neigh, Plumber then falling to the ground, covering his ears.

The Plumber then tries the sonic plunger on Will, trying to see if it works on defeating the Horse-Itus. The Plumber then commands Will to stop, and then Will says "You're not my dad", which is a reference to the vine "You're not my dad!". The Plumber then explains to an infected Will that he was the one who defeated the lonely demon, Enturroth, and every other enemy leading up before this episode.

The Plumber then confronts him and asks Will a bunch of questions relating to the cure of Horse-Itus. Plumber gets the answers he needs, then takes Will to the T.O.I.L.E.T., where he introduces his friend, 'grass shake'. He pours it into Will's mouth, in a minute, curing him. After Will is cured, he does "Gangnam Style" for the Plumber.

They then must shut off Ryan to conserve battery power. They then go the year 1762, the year Will was born. They arrive, and walk around his homeland.
