Operation: H.O.T.S.T.U.F.F. Codename: Kids Next Door : Season 5 Episode 18

Before the theme starts, Kani tells his eldest daughter, Kuki, not to touch the thermostat even though the house is unbearably cold. After seeing the thermostat's temperature dropping to colder temperature, Kuki decides to touch the thermostat and make things hotter. The next day, the other Sector V agents are gathered for a meeting. Nigel goes jabbering on about cauliflower being rainbow monkey brains. The rest of Sector V doubted this and, while Nigel jabbers on, Kani comes in and tells the agents about Kuki turning up the thermostat. Nigie leaves Wallabee to guard Kani. The rest of Sector V shows up to Kuki's house which is now transformed into an active volcano and ready to explode. Rachel suggests sending Sector P in Pompeii to turn down the thermostat as they have more experience with volcanoes but Numbuh 1 disapproves of this since Kuki is a member of their sector.
