Plot
Note: This movie is split up into four parts about the length of a standard TV episode.

The movie opens up to the events of "Behold! Tribe of the North!", in which SpongeBob, Patrick, and Sandy find out they are destined to become great warriors. They meet Frugrum, Sensei, and the other warriors, and challenge each other to a race around Swiss City.

It then continues on to the events of "Behold! Training Begins!", in which SpongeBob, Patrick, and Sandy begin training as warriors.

"Behold! A Dangerous Teacher!" is where events start changing. Patrick discovers the new teacher is evil, but SpongeBob is secretly falling for her at the same time. Patrick attempts to kill her, but SpongeBob stops him from doing it, as he reveals his attraction to her. They run off together at the end of this part.

The next part is entitled "Behold! Saving SpongeBob!". Patrick and Sandy run off away from Swiss City to save SpongeBob, who has run off to The City of Blood to marry the dangerous teacher. It turns out, SpongeBob is being mind-controlled by the teacher, so Patrick and Sandy have to kill the teacher in order to save SpongeBob. They then talk about how wrong it felt to take a human life as opposed to a monster life, as they reveal their love for each other and kiss at the end of the film.
