Rise of the Snakes is the first episode in the first season of LEGO Ninjago: Masters of Spinjitzu. Along with "Home," it debuted in the U.S. on December 2nd, 2011.
The four Ninja are snapped out of their post-hero complacency when Lord Garmadon's young son Lloyd shows up and tries to pick up where his father left off. The Ninja dismiss him as a threat, but regret that choice after Lloyd wakes up the evil snake tribe. A prophecy is revealed that states a green Ninja will ultimately defeat Lord Garmadon.
Introduction
Long before time had a name, the First Spinjitzu Master created Ninjago using four elemental weapons. But when he passed a dark presence sought out to collect them all; Lord Garmadon. So I, Sensei Wu; his brother, sought out to find four ninja to collect them first...
Plot
In the Monastery of Spinjitzu, Sensei Wu is interrupted from his meditation by the sound of the Ninja fighting. As the cries of battle continue, he enters the training yard only to find it deserted. Wu follows the shouting into the living room only to find them all playing video games. Just as they are about to perform a special attack, Wu unplugs the TV and implores the Ninja to start training again to prepare for his brother's return to Ninjago, as ever since Lord Garmadon has escaped, they have done nothing but play video games and waste time. Jay complains that peace is boring as they have no one to fight but Sensei Wu lectures the four on "not putting off until tomorrow what can be done today," saying that the four have not yet reached their full potential. Cole then uses the Scythe of Quakes to plug the TV in and the Ninja resume their game as Zane assures their sensei that they will be ready when Lord Garmadon returns.
Their meeting is interrupted by Nya, proclaiming that Lord Garmadon was spotted in Jamanakai Village, sending the Ninja to a state of panic. They rush down to the pen where their dragons are kept though have great difficulty mounting due to how out of shame they are. As they eventually take off, Nya question whether they will ever unlock their true potential, but Wu assures her they will in time.
As the Ninja fly towards Jamanakai Village, they reflect on what their sensei has just told them and decide to race to the village. They arrive on their dragons to stop Lord Garmadon, only to find the sighting to be his son, Lloyd Garmadon, who has escaped Darkley's Boarding School for Bad Boys again.
Lloyd tries to terrorize the village and rob them of their candy, threatening to release the Serpentine on the villagers, but is instead run out of town by the Ninja. Before returning to the Monastery, Kai discovers he has accidentally taken Sensei's bag in the rush, and finds a scroll that tells of the prophecy of the Green Ninja.
None of the Ninja are able to contain their excitement, boasting to the others that himself will become the Green Ninja. All consumed by selfishness, they try to hold a tournament to find who is the best of them all, and thus become the Green Ninja. Unfortunately, the idea backfires when Kai's Sword starts an elemental fire which cannot be put out. Zane attempts to freeze the fire, Jay has a flame on him, and Cole hits the fire with his Scythe. Sensei Wu arrives and uses the Shurikens of Ice to stop the fire, before explaining the Ninja must agree to continue their path to unlocking their potential before any of them will become the Green Ninja.
Meanwhile, Lloyd wanders the frozen wastelands of Ninjago, upset his plans have gone awry. Mistakenly, he uncovers an ancient tomb containing a tribe of the real Serpentine known as Hypnobrai. Slithraa attempts to hypnotize Lloyd, but he ducks out of the way and the General is met by his own reflection in an ice stalagmite, accidentally hypnotizing himself in the process. The tribe is now under Lloyd's control, who sends them to steal all the candy in Jamanakai. The Hypnobrai use their power to hypnotize the villagers, bringing more power to Lloyd.
Sensei Wu senses the presence of the Serpentine with his Spirit Smoke and quickly alerts the Ninja, who rush to the village and are able defeat the Hypnobrai, forcing them to retreat. However, Skales, the second-in-command of the tribe, hypnotizes Cole before leaving town, forming a scheme to destroy the Ninja for revenge. After stealing the Hypnobrai Staff, Nya uses the anti-venom inside it to cure the villagers, but Cole remains under Skales's influence.
The game played by the Ninja is actually a scene from "The Golden Weapon" in the US version. However, in the version aired in Germany, they are playing LEGO Battles: Ninjago. Additionally, in other versions, Zane is found eating the sandwich in the fridge instead of simply leaving a note behind.
The episode name refers to Lloyd unleashing the Hypnobrai, marking the Serpentine's first return to Ninjago since their last defeat. More broadly, it can refer to Lloyd's actions beginning a chain of events that will unleash all of the Serpentine and their "god" upon Ninjago.
Errors
When Jay says, "Why would you do that? Why?" Zane's mouth moves despite not saying anything.
When Cole leans back saying "we can train tomorrow," he says it in Kai's voice. Likewise, later on in the episode, Kai has Cole's voice when he's reading the Green Ninja scroll.
Sensei Wu kicks Cole's pizza out the doorway, however, it disappears soon afterwards.
