The villagers have unearthed a Fangpyreskeleton. Nya is conducting an experiment using it to try and reverse the effects of a Fangprye bite without the anti-venom in the Staff. She finds that it's possible to reverse the effects by raising the victom's heartrate.
After observing it, Kai, Cole, and Zane head off but Jay stays behind with Nya. He nervously asks her out on a date, which she accepts. When Jay is doing a victory dance, he pricks himself by accident on the Fangpyre skeleton's fang, unaware that the venom gets in his hand and begins to turn him into a snake.
Meanwhile, in the Realm of Madness, Master Wu tries to talk with Lord Garmadon about Lloyd and how he had gotten captured, but Garmadon doesn't listen, and they have a fight. Garmadon uses a double-bladed spear, a scythe, a staff with a shuriken attached, and a regular staff, while Wu uses his katana from their youth.
Wu attacks, but Garmadon counters with all his weapons, and forces Wu off the ledge they are on. Wu falls in the mud, and Garmadon calls his Mud Monsters. Wu uses his Spinjitzu on them to knock them out, but Garmadon sends more. Garmadon tells the Mud Monsters to converge and they all come together and overwhelm Wu. He barely pokes his head out of the mud coverage to inform Lord Garmadon that Lloyd is in danger.
Master Wu sinks in but Garmadon grabs him and pulls him out. Garmadon asks what Lloyd has done and Wu explains. Garmadon agrees to go back to Ninjago to help Lloyd, temporarily forming an alliance. Wu tells him that he's out of Traveler's Tea, so Garmadon informs Wu that the only way to get back to Ninjago is to climb the very dangerous Mountain of Madness.
Pythor and Aria head off to Mega Monster Amusement Park, to dig up the first Silver Fangblade. The Ninja find out that the Serpentine are at the amusement park, so Jay arranges the date there so he can fight, and have the date.
During Jay and Nya's date, Jay finds out he is turning into a snake due to the bite and heads towards the restroom. Meanwhile, the Ninja go to the ghost ride, where they find the Serpentine who have already dug up the first Fangblade.
Zane accidentally freezes the three of them while he is in NRG mode, which allowed the Serpentine to escape. When Jay comes out of the bathroom, he can't find Nya. The customers of the restaurant think Jay is a snake due to him turning into a Fangpyre so they attack him. Jay goes to the bathroom and comes out with a scarf on his face so he can escape.
The Serpentine had already revealed Samurai X as Nya and chained her to a roller coaster which had heavily damaged tracks. Jay gets on it to help her but was unable to untie her. On the coaster, Jay reveals he's turning into a snake and Nya reveals she is Samurai X. Nya tells him that he doesn't have to try to impress her, as she likes him how he is. She then kisses Jay, raising his heartbeat and turning back into a human.
He unlocks his True Potential and with increased strength, and saves them. The Ninja and Nya gather and wonder where Master Wu is and what he's doing. Meanwhile, Lord Garmadon and Master Wu have reached the Mountain of Madness and prepare for their journey back to Ninjago.
