Back in Ninjago the Ninja were training the Green Ninja Lloyd who was trying to get use to his new body and powers. Training was about to start when Nya entered the room,"Guys! You won't believe who Master Wu just talked to." she said. "Hi Nya" Jay asked before Lloyd kicked him in the face,"Ow! Lloyd!" "Sorry I was in the middle of that one!" Lloyd apologized. "Who was it Nya?" Kai asked as he walk up to her. "He talked to Merlock." she said only get dull face from the others. "Who is that?" Cole asked confused. Sensei then appeared from behind her and said,"An old friend of mine and the magical wizard of Knighton" "Knighton? Isn't that the Kingdom where everyone worships knights?" Zane said. "Yes it is Zane my friend informed me Serpentine have been spotted there and kidnapped a junior knight named Robin." Sensei informed and had worry in his eyes.Lloyd became confused asked,"Why would the Serpentine kidnap a kid? Well besides me when I was little." "I have no idea but we must find the boy before something awful happens to him. The Nexo Knights are on their way but I'm sending all of you out there to help find him. The sooner we find the child the better." Sensei Wu said. "You got it Sensei come on guys we've got some scales to kick!" Kai said running off with the other three Ninja. "Sensei I feel like this isn't a normal rescue mission." Lloyd said as he felt off. "I would lie and say it was but you are right Lloyd. This rescue mission is very different from the others." Sensei admitted before he began walking. "Why?" Lloyd asked as he followed Sensei. "Because there is more at stake here." he replied. Lloyd watched confused about what he meant as Sensei left then went to join the Ninja search party.
In the sewers of Ninjago City Scales slithered to his hideout with sack still over his shoulder not moving anymore. Scales presumed since it wasn't moving anymore that the boy inside must've fallen asleep. He set the sack down and grabbed some rope before undoing the knot on the bag and opened it to see the boy inside asleep he must've been a heavy sleeper because Scales tied his wrists and ankles without the child waking up. Constrictor and Fangpire slithered up to Scales and said, "So we have the boy now what?" Fangpire asked a little impatient. "Now we send Garmadon a little message. Saying that we have his son and if he ever wants to see him again then to hand over his power of the Serpentine to us." "But what if he doesn't believe us?" Constrictor said. "Then we'll show him a picture of the boy." Scales replied then heard a groan. They turned to see the boy wake up, "Where?...Who?" Robin questioned as his eyes adjusted to the light, "Who are you?" he asked. "We are the most feared group the Serpentine." Scales said. "Serpentine?...Why did you guys kidnap me?" Robin asked as he wiggled in his bonds again. "So we can use you for ransom against your father Lord Garmadon." Scales replied sinisterly but was surprised when Robin starting laughing at him,"What are you laughing at?" he hissed in anger. "Garmadon!? My father really? This has got to be a joke. My dad is a dairy farmer and last I heard Garmadon is no dairy farmer." Robin said in between laughs. "What!? All of this work and you aren't even related to Garmadon!" Scales yelled in an outrage. "This is what you get for listening to an unreliable source." Fangpire said. "So are you guys going to let me go?" Robin asked panting a bit from laughing so much. "No! We are going to have to dispose of you." Scales said as he slithered to him. "What? No..wait why!? Just let me go! I won't tell or anything I swear!" Robin said as he squirmed away towards the rapidly flowing sewer water. "Sorry kid." Scales said before a black ninja kicked him in the head knocking him the ground. "Ready for a little kick butt!" Cole said in his fighting stance. "How did you find us!?" Scales asked. "Uh did you forget you tied me up in a subway station near here a few weeks ago!?" Jay said falling to the ground with the others. Scales sighed because that part completely slipped his mind till then. "Well you caught us Ninja you win-NOW!!!" Scales suddenly yelled to a Constrictor that popped out of the ground next to Robin and pushed Robin in the water. The ninja ran over the edge giving the snakes a chance to escape. "Zane use your ice to-" Kai was saying till Lloyd interrupted,"No if you freeze the water he'll drown!" "Then what do we-"Kai was interrupted once more when Lloyd dived into the water. "Lloyd!!!" the ninja screamed as they saw their youngest member get carried away by the current. "This is so gross." Lloyd thought before taking a deep breath and diving him he searched through the water till he was almost out of air and resurfaced. He took another deep breath and tried once more searching till he caught a glimpse of peach hair. He swam towards the hair and noticed that the boy was completely unconscious he wrapped his arms around the boy and resurfaced to see them super close to a waterfall he tried to grab on to an edge but there was nothing to grab on to. Till a familiar hand with a red sleeve grabbed his he smiled at the sight of Kai and Kai smiled back before calling to Cole,"Pull!" Cole pulled to linked ninja out of the water one by one till all of them were safely out of the water. Lloyd looked down at the boy in arms and noticed something was wrong, "He isn't breathing!" Lloyd said in realization before quickly setting Robin down. His pinched the kid's nose before he breathed air into his lungs he looked and saw no result. Kai knelt down next to him and started pumping the Robin's chest. "Do it again!" Kai told him and he did again still nothing. He did it a final time and the boy cough up water. Everyone sighed in relief and watched as the boy's eyes began to flutter open. Robin continued to cough sitting up,"What happen?" he asked as Kai untied his hand and ankles then he held his head. "You were shoved into the water by one of those wimpy snakes." Cole said as he looked at the exit where the snakes escaped. "We're the ninja your friends sent us to come rescue you." Kai told the boy helping him stand up. Robin tried to as well but he was a bit lightheaded so he was a bit wobbly. Cole notice and walked over to him crouching down,"Hop on. Don't worry I don't bite." he assured. Robin smiled and climbed on Cole's back holding on tight as Cole stood up. "Come on let's head back to the bounty." Kai said then they began walking out of the hideout. "I don't think we ever introduced ourselves I'm Cole by that way. The red spiky hair ninja is Kai, the white nindroid is Zane we call him nindroid because he's a robot, the blue ninja with the squeaky voice is Jay, and the blond haired one in green is Lloyd." Cole said. "Hey my voice is not squeaky!" Jay replied crossing his arms. Robin smiled and said,"My name is Robin." "Nice to meet you Robin. Do you know why the Serpentine kidnapped you?" Kai asked. "Oh they said some really stupid and ridiculous stuff about using me for ransom against Lord Garmadon." Robin answered. "Why would they use you?" Lloyd question but Robin shrugged his shoulders, "Dunno they said something about him being my dad." Robin said which caused the group to stop in their tracks. "What? Another little Garmadon? No way I'm not dealing with another brat." could be heard amongst the group. "Guys. Calm down I think I would know if I had a little brother." Lloyd said. "But weren't you abandoned as a toddler at that school for bad boys."Jay said. "Either way we shouldn't be assuming remember what Sensei said about the power of rumors." Kai reminded. The ninja looked at each other knowing he was right. "Come on let's get back to the Bounty." Kai added as the group made their way out of the sewers.
