Cadence, also known as DJ K-Dance or DJ Cadence (pronounced dee jay ka-dense*), is a local Club Penguin DJ and a great dancer. She is a peach colored penguin who has purple hair with pink tufts, green headphones, a pink and yellow scarf, a pair of pink and yellow wristbands, black eyelashes, along with white and black shoes. She does not have any body items, however. Cadence and others like to think of her as a cool penguin, usually indicated by the hip attire and the way she speaks. Her favorite phrase is, "It's time to dance!". She likes to call herself the "Dance Machine". Like Rockhopper, the Penguin Band, Gary, and Aunt Arctic, she waddles around Club Penguin Island giving out a free background. Penguins using a cheating device such as Penguin Storm can get her hair, bangles and shoes, but this is cheating, which is against the rules.
Captain Rockhopper (commonly known as Rockhopper) is a friendly pirate penguin that regularly sails to Club Penguin via the Migrator (usually about every three months or so); accompanied by his red puffle, Yarr. His ship is always docked at the Beach. He keeps a journal of his adventures, and sells rare items brought over from Rockhopper Island. When he comes to Club Penguin, he always gives away a free item in the Pirate Catalog. Players can sometimes see Rockhopper in random places in random servers when he lands in Club Penguin. Players can receive a free gift from Rockhopper from his player card. Rockhopper is named after the real-life Southern Rockhopper Penguin.
Club Penguin has a multitude of servers, and Rockhopper can be hard to find. Trackers are not an option, because they are fake, but some work with lookouts on servers. Every time he comes, he brings a new free item with him, in the Ship Hold.
Sensei, (formerly known as ?????? when he was shoveling out snow, before the Card-Jitsu game was released), is a penguin that first appeared when the Dojo got severely damaged by lightning, claiming to have returned from "a long journey". He used to be seen at the Dojo Exterior, but now he can be found inside the Dojo, sitting on the cushion next to the variable-colour pot. He has the color Gray, which is not currently available to players and appears to be a very old Penguin. He has a small white beard (Possibly he is related to Rockhopper), thick white eyebrows, and a conical straw hat. He was seen digging out the Dojo. He later revealed he would launch a card game for training Ninjas, known as "Card Jitsu". His name was revealed to be "Sensei" or the Japanese word for 'teacher', implying he is the ninja trainer. Apparently, he said that came over from far away to return, which means he has been to Club Penguin before. He presently is handing out Starter Packs in the Dojo to players training to become ninjas. He also awards penguins colored belts for their progress in the Card Jitsu. Also, once players get a black belt, Sensei can be challenged and if one wins, they become a true Ninja. Sensei will always pick the opposite card of what you pick, unless you are a black belt.
On July 3 to July 5, Ninjas were able to meet Sensei at the Ninja Hideout, and teach them a new trick (a cloud maker). The award for finding him is an autographed background. He was also seen during the Sensei's Scavenger Hunt, teaching ninjas about the upcoming event. He also visited the Fire Dojo and Ninja Hideout on Friday 20th November 2009.
The Penguin Band is Club Penguin's official band. It is made up of four penguins. There once was a scavenger hunt when penguins had to find the Band's instruments. Once players found the instruments, their penguin was rewarded with a player card background featuring the band. Another background was given out during the Music Jam party when the band went on break. Like Rockhopper, the band members can be seen sometimes during certain parties, on random servers signing autographed backgrounds and talking to penguins.
Gary the Gadget Guy (more formally known as Agent G), is Club Penguin's only inventor and scientist and also the owner of the Sport Shop. He likes wearing a white lab coat and his special twisted spectacles, and enjoys eating Fish Dish Pizza, Cheese pizza, and a combination of icing, sugar, hot sauce, jelly beans, and Fish Pizza. He is almost always seen drinking Coffee. It is rumored that fine-tuning the coffee machine to play music while the coffee was brewing was one of his first projects. It's not known how Gary has his eyes. In an issue of The Penguin Times his eyes appear like Sensei's, but smaller. On Club Penguin Times issue 200, it was mentioned that Gary will make an appearance at the Festival of Flight 2009, and in the section "In Focus: A Waddle Down Memory Lane", Gary was quoting the quote at the top of the page. When the Volcano created a gigantic cloud across Club Penguin during October 2009, Gary said the Cloud might just create a Storm just in time for the Halloween Party 2009, and said he might have to investigate this Storm.
