Romeo wants to make his grandfather, Doctor Undergear, proud of him by sinking the Mighty Colossus with his new inventions, his Spark Shark Missiles, along with his Shark Sword, and his mechanical pets Shark Ship and Crab Bots, and if it's the last thing he ever does, but not if Kwazii's Atlantic powers and the PJ Masks help Captain Jake and his crew protect it.
The episode begins with happy laughter at Romeo's mansion where in his bedroom, Doctor Undergear who is happily visiting for the weekend, is helping his favorite scientist and grandson, Romeo, get ready for bed and tucks him in his bed. Then, before Romeo can go to sleep, Undergear tells him a bedtime story about Captain Colossus and his ship, the Mighty Colossus.
After Doctor Undergear is done telling his story, Romeo's pets are asleep and Romeo asks what was the Mighty Colossus was as his grandfather explains about it. He also explains about the time he tried to sink it to get new parts from it, but he was stopped by Captain Jake and his crew, and with a sigh, he wishes to sink the Mighty Colossus to get new parts from it.
When he left, Romeo tries to go to sleep but is thinking about the sad expression on his grandfather's face that he can barely sleep. He then decides to do something to make Doctor Undergear happy so he decides to call on his mechanical pets and invent something new, and even evil as always!
That morning at Starlight Beach, Kwazii, Connor, Amaya, and Greg are checking out the Mighty Colossus. Turning to Captain Jake, Connor compliments that the Mighty Colossus is the most amazing ship ever while Greg thanks him and his crew for inviting them to ride their ship tonight as the PJ Masks. It just might be their first time. Plus, they will be seeing the most beautiful magical sea creatures on the sea while watching the full moon.
Taking their thanks, Captain Jake tells them that it's the least he and his crew can do for their friends and they are also excited for tonight as well, but before they set sail for tonight, the gang will have to clean up the Mighty Colossus' deck so everyone geats to work as Kwazii summons his Magic Cleaning Brush that turns into a mop and it starts to mop the whole deck while Connor helps Captain Jake polish the cannons, Greg and Cubby work to empty the barrels of rotten coconuts, and Amaya and Izzy wash the windows while Skully does the dusting. After they are done cleaning, they are all set for tonight and so was the Mighty Colossus!
Later, nightfall comes, and Connor, Amaya, and Greg transform into Catboy, Owlette, and Gekko. Then they head to their headquarters and take the Gekko Mobile. Gekko drives it to the Starlight Beach's water and parks it next to the dock as he and his friends see the Mighty Colossus and hop out of the Gekko Mobile to meet Captain Jake, Kwazii, Izzy, Cubby, and Skully on board.
After leaving the dock, Izzy and Cubby let down the sails, Gekko helps with the anchor, and Captain Jake turns the wheel to start driving the ship into sea. Then, as they are sailing, Kwazii catches sight of the full moon rising into the night sky and everyone join him to see how beautiful it looked, but that wasn't the only best part! Looking down, they see some amazing creatures like Sea Lions, Sea Horses, and even Mercats, plus Sea Wings the Mercat! Everything is smooth sailings for everyone, when all of a sudden...
Something bangs on the Mighty Colossus with a mighty force, and it snaps everyone out of their thoughts as they go to look down at what was causing all the ruckus! Captain Jake and Kwazii decide to check it out as Kwazii spreads out his Aqua Wings and dives into the seawater while Captain Jake puts on his diving suit, hops into his splash diver, and joins Kwazii to find out where the missile came from.
As the pirate pals were searching, some kind of robotic spark shark missile is heading straight for them! Quickly, Captain Jake pushed Kwazii out of the way in time just as they turned to see the villain who was about to fire another missile: Romeo! Swimming towards him, his Shark, and his Crabs, Kwazii demands Romeo what are he and his pets were doing with the spark shark-like robotic missiles he shot at the Mighty Colossus.
Romeo explains that they are using his new missiles, the Spark Shark Missiles, to sink the Mighty Colossus since his grandfather, Doctor Undergear, never got to sink it because of Captain Jake and his crew defeating him and he almost got eaten by two Never Sharks! As he said that, Romeo scolds at Captain Jake and blames him and his crew for what happened and almost happened to Doctor Undergear.
With a sigh, Captain Jake apologizes to Romeo for defeating Doctor Undergear a year ago but tells him to not blame him and his crew for that because they were just trying to protect the Mighty Colossus from being sunken, and taken to Gear Island to have it's parts taken off. Kwazii agrees and tells Romeo that protecting things for people who used to own them is what a hero does, and then asks how he would like it if someone tried to break his lab and his other inventions.
He (Romeo) wouldn't like that at all, but that didn't stop Romeo from trying to sink the Mighty Colossus or doing what he wants, and he won't give up until he does so, and when it's sunken to the bottom of the sea, he'll use all the parts from it to make new inventions out of them, and he'll use them to take over the world! Captain Jake defensively replies to Romeo that he will never sink the Mighty Colossus like Doctor Undergear once did in the past year, and Kwazii adds that they'll never make things easy for him (Romeo). Not with what tricks they have up in their sleeves! With a scoffing laugh, Romeo responds "We'll see about that, Pirate Kitty Litter Man!" as he presses a button on his remote control and prepares to shoot another missile, but this time, it goes straight to Kwazii and Captain Jake!
Luckily, Kwazii is too fast for the missile as he summons his trident and swings the missile, then sends it flying back to Romeo's Shark Ship. Romeo drives his Shark Ship out of the way just in time and the missile hits a coral rock that then smashes into smithereens. Then, while Romeo is not looking, Kwazii summons his Atlantic Armor and prepares to protect his friend's mighty ship! Furiously, Romeo prepares more missiles and orders his pets to sink the colossus, but the more of them he fires at the Mighty Colossus or the pirate duo, the more Kwazii and Captain Jake fend them off with their powers.
Then they swim up to the surface and call out to their friends to defend the ship from Romeo's spark shark missiles as they salute, meaning that they'll do it and they work together doing their best while Kwazii and Captain Jake hold off more missiles.
While Kwazii and Captain Jake are keeping Romeo busy, Owlette and Izzy help Cubby and Gekko host the sails and Catboy helps Skully steer the ship out of harm's way, and out of Romeo's Spark Shark missiles! Meanwhile under the sea, Kwazii and Captain Jake do their best to keep Romeo's pets and missiles from getting one inch towards the Mighty Colossus or towards them.
Kwazii stomps on the seafloor to make a brinicle appear and freeze two of the Spark Shark missiles and Captain Jake lead some other missiles away from the ship, but while the pirate duo are distracted, Romeo found the chance to fire another missile towards the Mighty Colossus. As it is firing and zooming passed Kwazii and Captain Jake, it hit the ship straight onto the stem and shook the crew and the PJ Masks off their feet!
Getting up to his feet and groaning in pain, Catboy holds his grip back onto the ship's main wheel and turns with an annoyed look then cups his hand to his mouth to shout at Romeo that he will pay for firing his Spark Shark missile at the Mighty Colossus! Kwazii notices the hole on the Mighty Colossus and uses his repairing magic power to fix the hole in seconds.
Then he forms a protective shield over the Mighty Colossus before resuming his battle with Romeo and using his bubble blast to blast bubbles at Romeo's goggles, which prevents him from seeing. It gives Catboy some time to steer the Mighty Colossus away from Romeo and his Spark Shark missiles, just before Romeo pops the bubbles off his goggles and fires another missile!
Kwazii and Captain Jake think quickly as he (Captain Jake) fires a net at the first missile while Kwazii uses his snowflake stars and magic vines to stop the Spark Shark missiles from hitting them. Then, they swim off but Romeo was hot on their slipstream! They have to think of a plan fast, or the Mighty Colossus will not be the only one sunk when Romeo fires another Spark Shark missile at them!
Then, Kwazii comes up with an idea! Looking down at his friend, Kwazii asks Captain Jake if he still has any of the surprise cannonballs left in his ship only to receive a questioning glance. Kwazii tells Captain Jake to just trust him for that he has a plan to stop Romeo. Meanwhile, Kwazii's protection shield is beginning to crack open from the Spark Shark missiles' attacks as on deck, the PJ Masks, Izzy, Cubby, and Skully are holding on. At the rate they were in, the missiles will break through the shield and sink the Mighty Colossus for sure!
Just then, Kwazii and Captain Jake appears behind Izzy with surprise cannonballs in their hands and tells them that they should give Romeo something he won't forget as they load some cannons with the surprise cannonballs and ready to fire them at Romeo. As Captain Jake fired his, thick fog exploded out of the cannonball and made it hard for Romeo to see! Then, Kwazii his teleporting power to transport himself on Romeo's Shark Ship to grab the remote control that helps Romeo fire his missiles and crush it into pieces with his super strength.
Soon, the fog dissolves and Romeo finds Kwazii with the crushed remote standing right behind him. Enraged, Romeo grabs Kwazii by the wrists to wrestle with him, but then Kwazii uses his teleportation power to teleport himself and Romeo back onto the Mighty Colossus' deck.
Kwazii lets go of Romeo just for Izzy and Cubby to throw a net over him and have the nighttime villain trapped, but just as Romeo is trapped, he pulls out an exact copy of Doctor Undergear's shark sword and uses it's shark bite to cut through the net and free himself! Captain Jake quickly pulls out his mighty captain sword to fend off Romeo's shark sword and soon, they begin to sword fight!
A magic sword versus a mechanical sword!
As they were fighting, Romeo mocks, scowls, and scolds at Captain Jake to keep him from fighting with him, but all of that didn't stop Captain Jake from using his mighty captain sword, and their swords clash and clang together in their fight! Romeo's anger fuel his power and it makes it impossible for Captain Jake to fight him back as Romeo continues scolding and blaming at Captain Jake.
Then as Captain Jake is losing his edge, Romeo swings the mighty captain sword out of Captain Jake's hand, quickly catches it, and points his shark sword at him. Then, Romeo raises his shark sword and sends a sly grin down at Captain Jake as he prepares to slice him in half!
Before Romeo could do so, Kwazii defended Captain Jake from the shark sword's bite but Romeo pulled it away from Poseidon's Trident to block another attack from it. This time, Romeo and Kwazii continue fighting until Kwazii decides that he can't wait anymore. So, using his Trident, Kwazii tosses the shark sword out of Romeo's hand and into the air again!
This time, Kwazii uses his stretchy power to outstretch his arm and grab the sword away from Romeo. After getting the shark sword, Romeo groans and then starts tearing up in despair. Just seeing him like that suddenly made Captain Jake, Izzy, Cubby, Skully, Kwazii, Catboy, Owlette, and Gekko feel bad for him. Just then, Kwazii has an idea.
After wiping his tears, Romeo sees Kwazii and Captain Jake walk up to him, gave his Shark Sword back, and comfort him. Romeo didn't want this, but he felt better now. Then after getting off the Mighty Colossus, Kwazii uses his duplication power to make a duplicate of the Mighty Colossus so that way, Romeo can destroy the copy instead of the original while his pets help him rip the extra ones off.
Happily, Romeo goes back to his Shark Ship and starts firing his Spark Shark missiles at the Mighty Colossus copy, and soon got all of it's parts one by one. He then thanks the gang flatly, drove his Shark Ship, and went away back home with his crabs following them, while the PJ Masks and Captain Jake and his crew shouted hooray and jumped for victory.
The next morning, Romeo gives Doctor Undergear the Mighty Colossus copy's parts before he leaves for Gear Island, and with happy tears, he thanks his grandson and gives him a hug as Romeo hugs his grandfather back, while the pets hug them as well. Meanwhile outside, Connor, Amaya, Greg, Captain Jake, Kwazii, Izzy, Cubby, and Skully watch with smiles and happy to see that both their enemies are happy to get what they wanted.
