Underwater, just outside of Ninjago, a fish moves along before a shark suddenly appeared behind it and swallows it whole before turning away when R.E.X.'s lights shine at it as it moved along the ocean.

Inside R.E.X., the Ninja were all looking at the screen as Geoff was at the controls and Kai was shaking a bit. "We're almost to the Tomb of the First Spinjitzu Master." Zane said.

"Yeah, can't believe we're almost there after all we've been though." Cole replied.

"I can't believe I'm underwater." Kai said.

"You?" Maggie asked. "What about Cole?"

"Just how thick is this glass?" Cole asked as he knocked on the front visor.

"Careful, you might jinx it." Geoff replied.

"We're heading to your location now." Tania said on the screen as Misako, Cirrus and Dragon are behind her as well as Nya. "With Morro already ahead of you and able to foresee the traps protecting the tomb with the Sword of Sanctuary, it's going to be up to you seven to find the Realm Crystal before he does."

Jay nervously laughs. "Cole's a ghost, Kai can't swim, we have no magical sword and half of us have no Elemental Powers." He said before laughing again. "What could go wrong?"

R.E.X. passes by something big before something on it opens, revealing an eye as it soon looked down to R.E.X.

"I may not know the three tests you're about to face, but Misako and I discovered a riddle that makes reference to it that may help." Cirrus said on the screen before opening a scroll. "'A Spinjitzu Master can. A Spinjitzu Master cannot. To move forward, don't look ahead to find his resting spot.'"

"That's food for thought." Cole replied.

Jay soon gulped as he saw the thing they passed by is a giant squid. "Speaking of food, we're about to be some!" He yelled as the squid pursues R.E.X.

"We have to go faster." Kai said. "Much faster!" Geoff moves the controls forward as the squid moves a tentacle, slamming it at one of the windows, causing it to crack. "Why did the tomb have to be underwater?"

"I guess I really did jinx it!" Cole said as he saw the cracked window.

"Hold on!" Geoff yelled as he moved the controls to the side.

R.E.X. turns left as the squid was still chasing after it.

"Argh, what kind of weapons is this thing equipped with?" Gewuji asked. "Apart from cancer sticks."

"Isn't there a bigger fish?" Jay asked. "There's always a bigger fish."

"We don't need weapons." Zane replied. "Aim for that rock!"

"On it." Geoff said as he turned the controls.

R.E.X. comes up to a rock with a hole before going through it as the squid sticks its tentacles through the hole, but ends up stuck as R.E.X. moves away from it.

"Yes, its testicles are stuck in that rock!" Gewuji said as they soon cheer.

"Gewuji, they weren't a man's b-" Zane was soon cut off.

"Don't mention it to my sister!" Geoff yelled. "She knew they were tentacles, she was making a joke." (A/N: That little thing about octopus' tentacles being mispronounced was on a show I once watched as a teen. I think it was Beauty and the Geek Goes Tropical, the Australian version) He soon taps the console. "Attaboy, R.E.X. Guess Ronin has been taking really good care of you."

Jay still looked at the trapped squid a little. "Heh, it may not be a bigger fish, but at least we plugged the hole." He said to himself before chuckling a little.

In a room, Morro forces Lloyd ahead as he turned to him with his hands tied at the front with a Vengestone chain. "Morro, you don't have to do this." He said.

"Save it." Morro replied. "Your friend already made a foolish choice by forcing me to possess his body. Besides, with your other friends gone, it's just you and this wannabe." He soon looks at the Sword of Sanctuary to see reflections of many traps coming out and sighs.

Underwater, R.E.X. prepares to surface as it soon enters a cave before the windows open and the Ninja come out. "You wanna hide a tomb, this looks like a good place." Cole said as they look on. "We're here."

Jay groaned as he sees a bit of green cloth snagged on a branch. "There goes any hope Morro couldn't find this place." He said as he took the cloth and looked at it.

"Hey, stay positive." Kai replied as they look on to see footprints. "We're about to risk our lives going through traps we know nothing about, and all we have to rely on is each other. At least feel lucky we go this far."

"Oh, I'm sorry." Jay mocked. "You're right! What was I thinking? Hey! There goes any hope Morro couldn't find the tomb! We're not alone! Yay! Now we're gonna have to fight him again! Sure, we got our tails handed to us last time, but you never know in the future, 'cause Ninja never quit! Better?"

"Uh, I'll take it."

"Look." Gewuji said, pointing to a statue.

"The First Spinjitzu Master...creator of Ninjago." Geoff said.

"Whoa!" Kai said.

"Destination reached." R.E.X.'s computer said as the windows soon close up. "Auto return initiated."

"Auto return?" Jay asked as R.E.X. starts to go down. "No! No!" They run up to the bank of the water, but they stop as R.E.X. was completely gone.

"R.E.X.!" Geoff yelled. "Get back here!" He whistles its summoning tune, but it doesn't surface. He tries again, but it still doesn't work. "Damn you, Ronin, you stupid cancer stick inhaler!"

"Our Aeroblade weapons were in there." Zane said.

"Not to mention our only way back." Maggie replied.

"Hey, stay positive!" Jay said. "Who needs a way back when we gotta go that way?" He points to the path behind them.

"No sword, no powers, no problem." Kai replied. "We can do this, guys. As long as we got each other, right?"

"Brother sharpens brother." Cole said.

"And sister sharpens brother." Gewuji said.

"And also brother sharpens sister." Geoff replied. They soon prepare to head down the path as Kai sighed.

"Wait, there's two sets of prints." Maggie said as she knelt down.

"Lloyd's a size 10 and there is also an 11 and a half." Zane replied.

"Maybe Morro is holding Blake hostage." Jay said.

"Then we better hurry and rescue him along the way." Kai replied as they continue to walk down the path as it was lit by something on the walls which glows.

They come into a room with many doors and look around to see different symbols on them as well as a statue of someone poising, while holding a crystal and the door closes, causing them to turn around. "This could be the first test." Cole said as they look around.

"Oh, why did it have to be tests?" Jay asked. "Why can't the tomb just be protected by dragons? We're good with dragons."

"Don't remind me about dragons. I really miss Rocky."

"I think we're supposed to pick a door, but which one?" Geoff asked.

"What was it Cirrus said?" Maggie asked.

"'A Spinjitzu Master can." Zane started to recite. "A Spinjitzu Master cannot. To move forward, don't look ahead to find his resting spot.'" They soon start to look around the place while Jay started counting all the doors around them.

"A Spinjitzu Master can." Kai said, thinking about the first riddle. "Can what?"

"18 doors." Jay said as he finished counting the doors. "For 18 realms?"

"Well, could be." Gewuji replied. "But let me guess, pick the wrong door and we'll be in a realm of hurt."

"Or a realm of hell." Geoff said.

Jay soon groaned. "I wish we had the sword right about now." He said.

"We can figure this out." Kai replied. "A Spinjitzu Master can. Can." Gewuji soon sees a tornado symbol on a door.

"The symbol above this door, it's a tornado." She said. "This could be the one, right?"

"Hm. You could be right." Gewuji soon went over to the door and prepared to open it.

"Gewuji, wait!" Zane yelled, making her stop as Zane looked around for P.I.X.A.L. to analyse the statues.

"Picture recognition analysing." She said from inside Zane's head. "Pattern discovered."

"Step away from that door, Gewuji." Zane drags her away from the door.

"Uh, what is it?"

"We're inside a zoetrope."

"A zoe-what?" Maggie asked.

"A zoetrope." Geoff replied. "Zane must've realised that the engravings in rapid succession creates a moving image."

"I don't get it." Cole said.

"Think about it. 'A Spinjitzu Master can'."

"Do Spinjitzu!" Kai realises.

"Exactly!" Zane replied as the others back away for Zane to do Spinjitzu. In the Spinjitzu tornado, Zane sees as if the statues were just one as it starts moving its crystal around, creating a zoetrope image of a yin and yang symbol. "He's creating some sort of shape." He soon disperses and points to the door with the symbol. "That one. That's the door out."

"I don't know, Zane." Cole said.

"Yeah, isn't that the same door we came in?" Maggie asked. "Are you sure?"

"Are you sure you want to doubt a Nindroid?" Zane asked.

"Open the door." Kai said to Geoff. "Let's find out." They soon came up to the door as Geoff soon pulled on the handle.
