Operation: C.A.K.E.D.-T.W.O.: Like at the beginning of C.A.K.E.D., the Delightful Children From Down The Lane all have a bunch of kids singing the Delightfuls' variant of the "Happy Birthday" song. But this time, they are bound by ropes to their chairs. The Delightfuls selfishly say the kids have to partake in the annual tradition of them eating their cake, while the kids get nothing. The KND then burst in on their STANK (Super Transforming Armored Neighborhood Kruiser) to steal the Delightfuls' cake and share it with everyone except the Delightfuls. However, they soon discover that the Delightfuls and the cake are just holograms. Numbuh 4 notices the Delightfuls escaping in a giant aircraft. The KND quickly chase them in the STANK, forgetting to untie the kids in the mansion. The KND don't want to destroy the DCFDTL's plane because that would destroy the cake, so instead Numbuh 1 manages to get onto their ship and open a hole in it. He gets inside and notices the DCFDTL in the cockpit. Behind them is the cake. He uses a string with bubble gum at the end to latch onto the platform the cake is on and drag it to him. He decides to take a sample bite, only to find that it's actually made of metal. On the cake is written the words "Bye bye." Suddenly, the cockpit of the plane separates from the rest, leaving Numbuh 1 back in the plane. Numbuh 1 manages to get to the outside of the plane and uses that bubble gum thing to connect himself to the cockpit. He climbs the rope and gets into it. He bursts in, only to find they're not the Delightfuls at all... just some kids dressed up as them. One of them happens to be... Lizzie?! She says hi to Numbuh 1, and then says "I bet you're wondering what I'm doing here, huh?" To which Numbuh 1 replies, "Um, yes. That and why nobody seems to be steering this ship." The ship crashes and everyone gets out. Lizzie tells Numbuh 1 that the Delightfuls said they could have a taste of the cake's frosting if they tricked the KND into following them. Numbuh 1, understandably, gets really upset about this. Lizzie gets really sad and says she's really sorry, but Numbuh 1, still traumatized, doesn't forgive her. One of the other Delightful-impersonators says that Numbuh 1's being too hard on her, because she said she was sorry. "What choice did she have?" he explains. "Otherwise, she'd just be tied up at the stadium watching the Delightful Children eat their cake on a jumbo-tron like all the others." Numbuh 1 takes notice of this and leaves with the rest of the KND (who have just landed) to go to the stadium. At the stadium, a lot of kids are tied up in the seats while the Delightfuls are bragging about how they and only they get to have the cake. The KND suddenly land in the stadium and Numbuh 1 says that everyone except the Delightful Children are going to make sure that everyone in the stadium gets a piece of the cake. The Delightfuls suddenly rise up on this pillar (suspended them quite a bit above the stadium) and all the exits lock off. The cake suddenly comes alive and becomes a really, REALLY big monster cake. The KND are about to fire their weapons, but the Cake Monster knocks them out of their hands. The Delightfuls all brag about how they'll always be one step ahead of the KND and how they took everything into account. Suddenly, Lizzie swoops in flying the battered cockpit of the giant ship from earlier. The ship flies straight into the Cake Monster, causing it to explode. Pieces of the Cake Monster go flying all over the stadium, and everyone but the Delightfuls (who are too high up for the cake pieces to reach and, naturally, take it very hard and start crying) get a taste of it. Numbuh 1 forgives Lizzie for posing as one of the Delightfuls. The KND leave the stadium while the Delightfuls all continue to cry. As they leave, they thank the Delightfuls for their cake and tell to bring enough for everyone next year.
Operation: S.P.A.C.E.: The story begins while the Sector V Team is taking a trip to the KND Moonbase in their S.T.A.R.W.R.E.C.K. vehicle. While listening to opera on the boombox, the channels change. The team grows irritated and tells Numbuh 3 and her sister that they should agree on a radio station and says they'll get in trouble for bringing Mushi for the trip. Numbuh 3 tells the team that her mom put her in charge of Mushi while she was working, so wherever she goes, Mushi goes. They hug and say "Best Friends!". The team notices that there is a KND Prison Transport Ship on screen. Numbuh 1 tries to contact them and wonders why there is no one responding. Mushi thinks that Space Aliens ate their heads and starts playing with the controls. This causes the S.T.A.R.W.R.E.C.K. to crash into the Transport Ship. Because of what Mushi did, they have to contact the Moonbase for help, but the communicator's not working. Numbuh 5 suggests they can get a fuel drive on the Transport Ship. When Mushi starts talking about space aliens again, Numbuh 2 and Numbuh 4 become a bit scared and insist that they bring weapons just in case and they go searching for the fuel drive. Numbuh 3 and Mushi, while listening to a radio, hears someone knocking the door. Numbuh 3 answers it and someone rushes into the ship and locks her out. While Numbuhs 1, 2 and 4 are searching for the fuel drive, Numbuh 2 says the search isn't going well and then, they hear growling. Numbuh 2 and Numbuh 4 think it's space aliens. Numbuh 1 thinks they're crazy until, the boys see two strange one-eyed green things. They think they're space aliens and run away. They run into Numbuh 3 and see their S.T.A.R.W.R.E.C.K. drifting into space, along with Numbuh 5 and Mushi. While the ship drifts through space, Numbuh 5 comes out of the bathroom and realizes that the team got the fuel drive going. The someone who got the fuel drive going was her sister, Cree, who used to be KND operative Numbuh 11 and we learn that the reason why she let her sister and her friends capture her was that she knew the KND were going to take her to the Moonbase and the minute she got there, she would use the access code she stole from Numbuh 5's brain in SUPPORT (little did she know, it was a dummy) to detach the Moonbase so it would crash into the sun, but before she can get there, the pilots got into a fight over trading cards and hit the "Blow up the engines" button. Cree and Numbuh 5 start to fight and Cree is going to blast Numbuh 5 into space. Mushi breaks up the fight in a very emotional way. Realizing that they were wrong, Numbuh 5 and Cree hug, but Numbuh 5 tricked Cree and sends her into the trash bin and is blasted into space. Cree tells Numbuh 5 she is so in trouble when she gets home as she's being blasted off. Mushi tells Numbuh 5 older siblings fall for teary junk, must be hormones or something. Back on board the Prison Transport Shuttle, Numbuhs 1, 2, 3 and 4 are fighting the space aliens until they knock them out and the moment the STARWRECK arrives, Mushi waves hello to the space aliens, only to discover they weren't aliens, but Numbuhs 92 and 93. They grow infuriated at the KND and see Mushi on board the ship and plan to rat them out to KND HQ and are seeing big, fat decommissions all around and demand the Sector V team they untie them, but Numbuhs 1, 2 and 4 shoot them with their weapons. The show ends with Cree reprogramming the trash bin rocket to change its direction to the Moonbase. She smiles wickedly as she says, "All according to plan..."
