Extended: The ninja arrive at the Explorer's Club where they hope to obtain the second Scroll of Forbidden Spinjitzu. They find themselves running afoul of bureaucracy at its worst, however, when the club manager refuses to allow them in (since they are not members) Zane uses abilities to try and pass himself off as Clutch Powers. But with no success. Finally, having no choice, the ninja decide to break in. Unfortunately, the Explorer's Club isn't quite as easy a target as they might have hoped. Security guards quickly pursue them and what might have seemed an easy mission is quickly complicated when the ninja accidentally unleash various evil artifacts and dangerousinsects that have been donated to the club by other explorers. In the end, the ninja succeed in obtaining the scroll, leaving the club in chaos.
The ninja tried again, but this time, they used Zane disguised as Clutch Powers. Once Zane entered the building, he is confronted by Putnam, who tells Zane that his membership had been suspended and cannot obtain any artifacts.
After the two failed attempts, Nya decided to be bold by sneaking in the building and stealing the scroll. Lloyd and Zane follow up, and all three reach the rooftop. The trio then shut down a fan by using Lloyd's sword and Zane's ice to prevent it from moving and made their way down the ventilator using a rope hook. Suddenly, the fan broke free causing the ninja to fall and crash into a middle of a meeting between Shippelton, Smythe, and Underhill. Lloyd tried to come up with an excuse by saying they were working on the air conditioning, but his sword came tumbling down. Shippelton knew he was lying and calls for security, causing the ninja to flee into a room.
After the ninja entered the room, they find out that it is one of the rooms that has artifacts, so they begin searching for the Scroll of Forbidden Spinjitzu. While probing, Lloyd knocked down the Chest Vortex and it began sucking in artifacts, but Lloyd stopped the mysterious relic by placing a glass cube over it.
After more searching, Lloyd came across the Mirror of Fears and it showed his greatest fear of becoming his father. For Nya, her greatest fear was just being a normal citizen, and for Zane, his greatest fear was having no life. While Lloyd was talking to Zane, something crawled on Nya, causing her to freak out and throw the mysterious object onto Lloyd and Zane. Then, the door opened and the security guards tried to seize the ninja, but they were able to enter another room.
Zane realized they entered the entomology room, prompting Nya to tell Lloyd to not touch anything, but Nya knocked down a glass containing Venomasicus Tigrus which happened to have the second-most painful stings. The ninja tried to outrun the sworn of wasps, but they are stopped by Cecil Putnam and his security forces; nevertheless, the wasps attack them. Putnam is able to get away from the wasps and shoots a blowdart at Zane, but it deflects off him and hits a glass holding Vastodectrus Venemous which happened to have the most painful stings. Amongst the chaos, Nya told Lloyd and Zane to regroup and they enter another room.
This time, Nya found the second Scroll of Forbidden Spinjitzu, so they wrapped it up and exited the building, leaving everyone else inside the Explorer's Club in disarray.
The mummy hand in the relic room has the appearance of a real-life human hand rather than a minifigure hand.
This could mean the hand was owned by a big figure (similar to Dogshank, Killow, and Krag) rather than a normal human, since they have real-life hands.
While the title card says "The Explorers Club," several sources list the episode as "The Explorer's Club," meaning the title card is erroneous, as with "Enter the Digiverse," or the title is written erroneously in sources outside of the show, as with "Ninjago Confidential."
