Junkberg is a dumpsite planet for all sorts of discarded mechanical parts. Planet Junkberg is also a place to buy and sell used equipment there.
The planet's abundance of old and used parts has lead to its inhabitants constructing an expansive city out of said parts. A huge market is placed at the entrance to the city with an assortment of vendors selling food and miscellaneous items, presumably scavenged from the planet's dumpsite.
Elsewhere, the BoBoiBoy's Gang received transmission from Tarung and Koko Ci on the TAPOPS spacecraft led by Papa Zola. Tarung praised BoBoiBoy for another successful mission and Koko Ci added that his popularity at TAPOPS has increased, making it more likely for new recruits to follow his example. BoBoiBoy insists their success is a team effort, this makes Fang frustrated as he still looks jealous of his higher popularity.
After the transmission, Papa Zola also congratulated BoBoiBoy for succeeding, believing it was because he was the boy's idol, but left Cattus to lead the ship in doing so. Cattus struggled to dodge the asteroid field, but Papa Zola intervened too late to avoid a collision that severely damaged their engine, preventing them from traveling too far. Gopal suggests teleporting instead, but Ochobot has used too many of power on their last mission to be able to.
While Captain Papa and Gopal panicked, BoBoiBoy housed the nearby Planet Junkberg, which is a landfill. Ying concludes that there must be a used market market on the planet where they can find something to improve their ship, so they go there immediately. Unfortunately, the engine is completely broken by the time they land, putting more pressure on their search. It is agreed that Captain Papa, Cattus and the girls stay behind to guard the ship against the swindlers while Ochobot and the boys (including a rude Fang) find the necessary parts.
At the supermarket, Gopal finds a food stand where Ochobot and BoBoiBoy told him that he is eating space lizard kebabs, causing him to try various extreme methods to get the taste out of his mouth. Fang allows others to flee in favor of investigating a stranger who waslentering the hallway. He witnessed an exchange between a foreign seller (the same foreign seller from the beginning of the episode), which Fang's glasses identified as Gijimo, one of TAPOPS' most wanted criminals.
At that moment, BoBoiBoy passed by and asked Fang if there was anything he wanted to tell them, referring to his earlier behavior. Fang set it aside because he was tired before he ran into the hallway to find a buyer, leaving BoBoiBoy to protest their split. He quickly discovers, ambushes and intimidates the aliens with his shadow power to reveal the existence of Gijimo, as well as discovering that the aliens bought a fake Power Sphera resembling GigiBot.
