We see Jake, Hanazuki, Captain Man, Kid Danger, Mega Man, Spongebob, True and Dedede inside pirate island with Hanazuki yelling
Hanazuki: Basil, where are
you?
The group then heard clattering from the map room and went there to see Basil trying to build another device and then he saw the group and said
Basil: Jake, Hanazuki, so glad you got rid of Mechrilla's musical machine
Captain Man: We helped too
Basil: sorry I didn't see you there, so, what do you need?]
Captain Jake: We were wondering if you know what a lightsaber is?
Basil: follow me
The group then followed Basil to his ship inside Bucky's grotto and saw him pull out a crate full of lightsabers but when Basil opened the crate the robot key in Eddy's pocket pulled him towards the pile with Ed, Marie, Sarah, Kevin, Terra and Ultron following behind saying
Eddy: Stupid key, what's wrong with it?
Basil: It's reacting to one of the lightsabers
when Eddy took out the robot key a lightsaber with a blue bolt for the ignition switch and when Eddy grabbed the lightsaber and hooked the robot key to the bottom of the lightsaber and it turned on showing a blue glow and then showed a hologram of silicon city with the same mysterious person from before in the lighthouse garden with Dr. Light saying
Dr. Light: So you're here to find the most determined person to hold this lightsaber?
Lord Obsidian: that is correct, and I sense he is around here somewhere
the two then turned around to see Lord Obsidian walking up to them with his hand out saying
Lord Obsidian: why not give it to me, I shall hold on to it.
Mega Man: Get away from them!
Obsidian jumped back when Mega Man landed in the garden and started shooting at Obsidian only to get punched into a tree when Obsidian got close and then Obsidian started walking over to Dr. Light and the mysterious person to get the lightsaber but the lightsaber started to float in the air with Mega Man standing up and caught the lightsaber when it came his way and turned it on and charged at Obsidian missing a few times until he got Obsidian by the knee and saw what he did and turned it off and gave it back to the mysterious person saying
Mega Man: that thing is too dangerous, even for me
?: But you have the heart to spare the life of the villain, you are worthy]
Dr. Light: worthy?
Mega Man: of what?
?: of protecting this key, once I find the other three, the key will teleport you to my place, see you soon
The hologram ended with Mega Man sighing until Jake pulled out the ocean key and a handle of a spatula went into Jake's hand and he hooked the key to the bottom of it and it turned on showing a green glow and showed a hologram of bikini bottom with the mysterious person at the krusty krab in Mr. Krabs office with the lightsaber on the chest like desk saying
?: Mr. Krabs, I am looking for the one that is determined to hold this
Mr. Krabs: I see, but what does this have to do with money?
? [this is a lot more important than money]
Mr. Krabs: yeesh, by the tone of your voice, I believe you, so does this thing do?
?: It's called a lightsaber, only the most determined can use it
Mr. Krabs: I sure feel sorry for whoever gets caught on the wrong end of... what was that?])
when Mr. Krabs and the mysterious person exit the office they saw Plankton in a giant tank and aimed it at Mr. Krabs saying
Plankton: Alright Krabs, give me the krabby patty formula or things are going to get ugly
Mr. Krabs [Spongebob!]
Spongebob: Yes sir!
Spongebob then jumped out of the kitchen through the window only to bet whacked at one of the poles with Plankton saying
Plankton: Ha! I told Karen that the speed gears would make this cannon swerve faster, now then, the formula
Mr. Krabs: I'll never give you the...]) Mr. Krabs didn't finish what he's saying when the lightsaber came out hitting him on the back of the head and went into Spongebob's hand when he stood up and turned it on and charged at Plankton's tank and sliced off the cannon and Plankton pressed a button launching him back to the chum bucket with Spongebob turning the lightsaber off and gave it back to the mysterious person saying
Spongebob: That thing's too dangerous to use, not even me]
?; But you are determined to protect this key, once I find the other two, the key will teleport you to my place, see you soon.
The hologram ended with Spongebob turning his smile upside down and then Hanazuki pulled out the rainbow key and a curved handle came out of the pile and into Hanazuki's hand and she hooked the rainbow key to the bottom and it turned on showing a yellow glow and showed a hologram of the rainbow kingdom with the mysterious person in the castle talking to Rainbow King saying
?: Rainbow King, I am looking for the one that is determined to hold this lightsaber
Rainbow King: I'm not sure how that will fit in with the rainbow kingdom, besides, we're a peaceful kingdom.
?: You should never jinx what you say.
Just then the doors of the castle came down when a bunch of dark soldiers and brutes charging in with the rainbow guards trying to hold them back until True and Bartleby came in and saw the fight and tried to run away but True got pulled into the air by a raygun held by Professor Purple and when Rainbow King thought the was done for the lightsaber in the mysterious person's hand started to float in the air and went into True's hand and turned it on and cut off the linc to the raygun and when she landed on the ground the dark soldiers and brutes charged at her only to get slashed down and disappear and then Professor Purple started shooting lasers at True until she reflected one of them at the raygun and then he opened a portal saying...
Professor Purple: This isn't over, we'll be back
when he went through and closed the portal True turned the lightsaber off and gave it back to the mysterious person saying
True: whatever that was, I don't think it would be a good idea to have it in the rainbow kingdom.
?: But you are determined to protect this key, once I find the last one, the key will teleport you to my place, see you soon.
The hologram ended with True putting one of her hands behind her head with Ultron pulling out the dream key and a long handle went into Ultron's hand and he hooked the dream key to the bottom and it turned on showing a purple glow and showed a hologram of dreamland with the mysterious person at Dedede castle in the throne room talking with Dedede and Escargoon saying
?:You're majesty, only the one most determined can hold this lightsaber Escargoon: And why would we want a lightsaber? we have a bunch a laser-saws.
Dedede: Quiet Escargoon! I wanna hear more.
?: I'm afraid it's all I have to say.
Escargoon [And you don't know where this determined fella is.
Dedede: shut up Escargoon!
Just then the throne room doors came down when a bunch of dark soldiers, brutes and a titan came in with a bunch of Waddle dees holding them back until Kirby flew over them with the fire ability and blew flames at them with Sword, Blade and Meta Knight clashing their swords at some of the soldiers with Dedede and Escargoon running from the titan but Dedede got stomped to the ground and couldn't get up with the titans foot on him until the lightsaber flew through the air and into Dedede's hand, turned it on and he pushed the titan off and swung the lightsaber at the titan and charged at the soldiers and brutes slicing through them and disappeared, when it was over Dedede turned the lightsaber off and gave it back to the mysterious person saying
Dedede: I don't want anyone to get hurt with this thing around
?: Good to know, you are determined to protect this key, this key will teleport you and the other three to my place, see you soon.
The hologram ended with Dedede gaining a tear in his eye with the four holding the lightsabers in their hands, we now go to gear island in Magellan's room to see Magellan on a massage table wearing a towel over her body and her hair laid out with Relaxer giving Magellan a massage until Grim coming in the room and covered his eyes when he saw Magellan with only a towel and then said
Grim Buccaneer: Magellan, the dark scouts brought in a report that Huntress's spirit is heading into a cave that is said to be abandoned.
Magellan: Abandoned? I may know what that place is.
Relaxer the green soldier: mistress, please, you're moving too much.
Magellan: Get some soldiers, brutes and titans ready, we're heading out!
Grim Buccaneer: I'm on it,
Magellan: Grim still had his eyes cover and was bumping into things until Magellan said
Magellan: uncover your eyes.
But when Grim did he saw Magellan and ran out of the room with Magellan feeling a pop in her spine and said
Magellan: that felt good.
Relaxer the green soldier: Like I said, I'm able to sense any tension in someone, the next joint in your spine is gonna take a while to pop.
Magellan: Take your time.
With Relaxer pushing his elbow against Magellan's back ends the chapter, another chapter ready
