|“Oh my, no! Rules are rules, after all! Where would society be without them? Hmm? We can't have anarchy, can we?”|
|— Cecil Putnam to Lloyd, Zane and Nya, "The Explorers Club"|
Cecil Putnam is an archaeologist and leader of the Explorers Club.
Cecil personally calls Clutch Powers, telling him that his membership has been revoked because he hasn’t explored anything in over 10 years. Clutch then tells him that he has stumbled upon a pyramid, and hangs up.
Cecil was by the reception desk when Lloyd, Zane, and Nya arrive, requesting a Scroll of Forbidden Spinjitzu. He refuses to give it to them because they are not members and throws them out. Zane, disguised as Clutch, attempted to get Cecil to hand him the scroll, but he tells him that his membership has been suspended. Later, the three ninja break in through the ventilation, unintentionally disturbing a meeting before Cecil and a group of guards came in to grab them. They escape, quickly heading into the artifact storage room. Once the three ninja were in the storage room where rare bugs were, Cecil and the guards attempted to capture them but were distracted by some Venomasicus Tigrus wasps that Nya accidentally released, but Cecil managed to get through them and tried to attack them with a blowpipe, but the dart ricochets off Zane and hits a nearby cage containing Vastodectrus Venemous, providing a distraction for the ninja to steal the scroll, leaving Cecil and the members no choice but to watch them leave while the Venomasicus Tigrus wasps kept attacking them.
Cecil wears reading glasses as well as a light brown suit with a brown vest and a matching striped bow tie, as well as a white shirt. His Explorers Club pin hangs on the left side of his blazer.
Cecil appears to be oblivious about situations in Ninjago City, or just doesn't seem to care at all, thus making him very selfish and self-centered. He also seems to have some form of a grudge against Clutch Powers, as he seemed to take joy in reminding "Clutch" that his membership had been revoked.
- He uses the same hairpiece as Dan Vaapit, originally used on Superman from LEGO's DC Super Heroes theme.
