Katakululu

Katakululu is a frog-like alien who used to reside in Planet Dargha'ya before being captured by Tarung. It first appeared in Episode 9.

BoBoiBoy Galaxy
He first appears in episode 9 as encounter a pair of glowing red eyes that hypnotize Adu Du.

Elsewhere, BoBoiBoy and Gopal set up camp for the night—having been forbidden from returning to the station by Koko Ci until they deliver the laundry bundles, otherwise, TAPOPS will receive no reinforcements—while Fang plans out the route to the delivery spot, which is one day’s walk away. The three of them remain in the dark as to who the recipient is. While they sleep, Adu Du and Probe are in another part of the forest, now sporting tribal outfits, weapons, body paint and in Adu Du’s case, glowing red eyes. He adds "lulululu" at the end of his sentence as a figure in the shadows watches him.

The next morning, the boys wake up by a rustling sound. Panicking, Gopal throws a rock at where the sound is coming from, only to have it bounce back and start bawling. This alerts nearby rock mounds, which turn out to be aliens with red glowing eyes. BoBoiBoy transforms into BoBoiBoy Earth to protect them from the Rock Monsters attack. Gopal's Food Transformation blasts are ineffective as they aliens are living creatures. The three of them make a break for it, but the Rock Monsters stop chasing them when they enter a clearing. Suddenly, Adu Du and Probe appear, the former calling himself Olu Lulu and adding "lulululu" to the end of his sentences. He accuses them of invading his territory and attacks with numbing blow darts, hitting both of Gopal's arms and Fang's leg.

In the ensuing fight, Adu Du exhibits his newly acquired fighting capabilities before capturing them and their laundry bundles after they fall into some mud that renders them immobile. They are tied to a stick carried by Mecha Probe, who privately informs them that he is still himself and it is only Adu Du who went crazy after being hypnotized by a frog. Probe remained unaffected since he is a robot, which is what he attempted to explain to BoBoiBoy earlier before he attacked him.

The group reaches where Adu Du calls into the forest in the "lulululu" fashion. A frog emerges and responds with an identical croak that Adu Du refers to as "[his] master, Katakululu." It hops over to Gopal and hypnotizes him, sending his consciousness to a sort of limbo between their minds where he can understand Katakululu’s croaks. The frog interrogates him as to why they are on Dargha'ya, and Gopal tells it about their mission, leading Katakululu to believe it knows who their recipient is. Probe takes advantage of the frog's distraction to free BoBoiBoy and Fang.

Outraged at his betrayal, Adu Du attacks him, only for Fang to stop him. Katakululu commands Gopal to protect it from BoBoiBoy. BoBoiBoy splits into Earth, Wind, and Leaf to defend against Gopal's frog-food blasts. He transforms one of Leaf's vines into a snake, which scares him and causes Leaf and Wind to waste their energy tossing the snake back and forth between each other. Earth traps Gopal in an Earth Grasp and advances towards Katakululu. With Adu Du being subdued by Fang and Probe, Katakululu summons the Rock Monsters—whom it has also hypnotised—to corner BoBoiBoy and Fang. It attempts to hypnotise them.

They're interrupted when the figure from the previous night—revealed to be sporting a TAPOPS insignia on his clothes—lands between Katakululu and the boys. He proves to be immune to the frog's hypnosis and stares into its eyes long enough that it blinks and hypnotizes itself, relinquishing its hold on its hypnotised minions. Adu Du recognises the newcomer in a terrified manner as Admiral Tarung and flees the scene with Probe. He explains to Probe that Tarung is a retired TAPOPS admiral known for his ruthlessness, despite him seeming mild-mannered earlier. Tarung confirms to the boys that he is their recipient by reading the S.O.S. message Koko Ci sent him on the laundry receipt—since only TAPOPS members can decipher those messages—and insists they leave for the station immediately.

Onboard Fang's ship, Tarung explains that he sends his laundry to TAPOPS because the encrypted laundry receipt messages are his only communication to the outside world, having ceased all other means since retiring. He was on Planet Dargha'ya as his hobby is tracking and researchig exotic animal species in order to better protect and preserve them, like Katakululu, which he has taken with him and blindfolded as a precaution. Tarung later preserve Katakulululu and bring him to TAPOPS Station.

Abilities

 * Using its eyes, it can hypnotize humans, aliens and monsters to obey him, to obtain information or for protection. However, this does not work on robots like Probe. Though, this ability can backfire and hypnotize itself if one can stare at it and resist its hypnosis ability like Tarung.
 * When in danger, it can call out to summon its hypnotized victims.

Trivia

 * Its name is a play on "Katak", which means "frog" in Malay.
 * All of its hypnotized victims will dress up as aborigines and add "lululu" at the end of their sentences.
