When they arrive, a humugous flying object appears. Numbuh 74.239 shakes his hand and both Nigel and Numbuh 74.239 are teleported to a secret location. Shortly after, though, the entire ride collapses from the damage, but Numbuh One emerges from the debris clutching the pipe and wins the scavenger hunt. As the pipe is knocked out of the Delightful Children’s hands by a sign, Nigel catches it and grabs onto said sign, while the Delightful Children fall into a broken part of the ride, and into a deep hole below. They shout why, and Numbuh 1 answers that the Kids Next Door will never end. They still continue to do so, but Numbuh 1 says he can't. They try to make him say it, but Numbuh 1 refuses. Numbuh 1 and the DCFDTL have their final confrontation in fighting over Father's pipe at a log river ride, and the Delightfuls are about to finish him off with Nigel's S.P.L.A.N.K.E.R., telling him that he's finished and it's the end for him.
He then makes his way to the amusement park while his teammates hold Father back and show the items they got from Sector W that were given to him, putting him in the lead. Furious, his teammates turn against him and Sonia gives Father's Pipe and the key to Sector W's transport to Numbuh 1. Despite being saved by Sector V, he can only say: "I WON! I got the pipe!". Numbuh 1 then inflates Numbuh 5's cap just before Father can stop him, and then he tips over and falls into the deep pit.Ī singed and dazed Numbuh 363 is asked if he is okay by Sonia. But then, Father goes into an uncontrollable rage and transforms into a fiery dragon and freeing himself from the B.E.A.R.H.U.G.G.A.H. He is later trapped by Numbuh 1 with a weapon called the B.E.A.R.H.U.G.G.A.H., buying them time for Numbuh 363 to grab Father's Pipe and escape. He throws a fireball towards the two sectors which created a deep pit on the floor but missed them. He was not happy finding them in his house and shouted that. After a short argument between Numbuh 1 and Numbuh 363 about teamwork, Numbuh 363 starts to freak out when Numbuh 1 touches him and shouts "DON'T TOUCH ME!", causing Father to wake up. Later, they found out that Sector W is going after the highest scoring item in the game, Father's Pipe, so Sector V arrives in DCFDTL's mansion not to get Father's Pipe but to rescue Sector W. Despite their best efforts, they couldn't seem to catch up and remain in dead last. Numbuh 1 thinks they should give, but is convicted otherwise. While Sector W holds the lead, all the others except Sector V catch up with them. Later, Numbuh 74.239 invited Sector V, W and all villains to the Rainbow Monkey Let's Learn About The Lavatory Amusement Park to announce that he has the cake and he will only give it to the winner of the scavenger hunt he held, and states that his purpose goes “beyond the Kids Next Door”. 74.239 will tell them, but ordered Father to release them or he destroy the cake and meet him the very next morning.
Numbuh 1 demands to know what test and who they are. Numbuh 74.239 tells them he and they took and only give it to them if they pass the test they came up with first. When they removed the sheet, they find, to their horror, Numbuh 74.239 casually lounging with the cake nowhere in sight. Things take a singular turn when they unveils the supposed cake. With nothing else to do, Sector V returns to their tree-house only to find that the DCFDTL and Father had taken over the base with a film crew and were going to eat the cake there out of spite and Sector V's treehouse as picked as a better backdrop. Numbuh 362 arrives on the scene to tell Nigel that his sector is no longer in charge of retrieving the cake and they are to be replaced by Sector W (led by her younger brother, Numbuh 363 along with Numbuh 83 and Numbuh 84 from Operation: T.R.A.I.N.I.N.G.), as well as all future cake retrieval missions, much to Numbuh 1's dismay and fustration, and took real hard. After a short chase, DCFDTL get away along with the cake. Numbuh 1 tries to put tracking devices on them but he is spotted. The Delightful Children From Down The Lane are once again trying to keep their birthday cake for themselves but as usual, Sector V will make sure that it won't happen.
The episode begins like any other C.A.K.E.D.
