Sergeant Major Kululu (クルル曹長 Kururu Sōchō) is the head of communications in the Keroro Platoon. His body is yellow in colour, with orange headgear that includes two headphone-like white pieces over his ears. His forehead and belly mark is a filled spiral. He also wears glasses with spirals on them. He first appears on the second volume of the manga, chapter 20, and in the 9th episode of the anime. Kululu was originally blue when he was little, but at the end of the short movie Secret of the Kero Ball, he became yellow, due to being stuck in a huge plate of curry that Keroro made for him from the Kero Ball. As a tadpole he had a pacifier and a bib.[citation needed]
Although he is of a higher rank than Keroro, he is not the leader of the Platoon due to his unpleasant and unnerving demeanor, which has given him the nickname of 'Yellow Devil'[citation needed]. Kululu is renowned to be enigmatic, deceitful, and downright evil, lazy and has a habit snickering at the beginning and end of a sentences. Unlike the rest of the platoon who specialize in combat, Kululu's expertise lies in his high-level technological prowess, including hacking and inventing, and has designed and created most of the gadgets and weapons used by the platoon. Being the least emotional of the Keroro Platoon, he is almost never seen being moved to tears or smiles by any events, though at the same time he rarely, if ever, panics when something goes wrong, likely due to the multiple dangers from his own inventions outweighing it. Although he smiles while being beaten or beating and or tricking (causing pain) to others.He encourages his abuse as long as he doesn't die or mess with his experiments. This was shown in 'How to Succeed in Pekoponian Conquering Without Really Trying' when Fuuyuki and Natsumi start punching him and he says "At least I got you to beat me. Come on beat me, I want you to, you want to, everyone wins." Kululu's Achilles' heel is Mois' pure heart. He has no defense against it, and when confronted by it, he's willing to do anything just to get her to leave although she is usually in his lab working with him or working for him.[
Keroro asks Kululu what his goal is, but he laughs his "Kukukuku" laugh that everyone gets scared and Keroro asks Tamama what his goal is to change the subject.
He is generally disliked by everyone, most of the characters seeing him as a disagreeable prankster ( except on episode "The Red String Theory" when Karara falls in love with him for saving her from her father) and, in the series, action figures of him tend to sell very poorly on Keron, (much to Kululu's chagrin) but Kululu seems to take pride in his bad attitude. When ever something bad happens to another character or is blamed for doing something, he laughs in a medium to high pitched voice saying "kukukukukukuku". Despite his attitude, he gets along quite well with Mutsumi, his human friend, and Aki Hinata, with whom he has a stalkerish crush on. Kululu and Giroro greatly loathe each other due to their vast differences (Brain vs. Brawn) and as a result, Kululu usually uses Giroro as a guinea pig for any invention that he creates. Kululu has a genuine love and talent for curry, but this is often taken to an extreme point where he can even bathe in it.
His name comes from the Japanese word for the phrase "round and round" ("kurukuru"), referring to the spirals seen on his glasses.[citation needed] His name may also come from the incurable brain disease named 'Kuru' The term "kuru" derives from the Fore word "kuria/guria", 'to shake' a reference to the body tremors that are a classic symptom of the disease; it is also known among the Fore as the laughing sickness due to the pathologic bursts of laughter people would display when afflicted with the disease.This may also refer to Kululu's insane 'Kukuku' laugh.
