Timmy: Come on, Poof! Show me tree! [he shows Poof a picture of a tree and Poof turns into a bee] Well, "bee" rhymes with "tree".
Wanda: [as a squirrel] Poof shouldn't be out in public like this until he has more control of his shapeshifting!
Cosmo: [as a squirrel] Don't feel bad, Poof. Daddy used to be a terrible shapeshifter, but now, watch me turn into a ping-pong table! [turns into a lion and roars. Game hunters pull up in a buggy and shoot him with a tranquilizer dart, making him fall asleep and into a net]
Game Hunter: Blimey! I caught a rare green lion! To the zoo, lads! [drives off with Cosmo]
Wanda: Uh, he's getting better. At least he has four legs this time.
Mark Chang: [pulls Timmy aside] Help me, Timmy Turner! My Fake-i-fier is, like, defective, and my hope is, like, that your powerful floating friends might, like, repair it! Like. [tranquilizer darts hit him] Oh, shya...
Game Hunter: Blimey again! A talking octopus with a glass-covered brain! [driving off with Mark] To the aquarium, boys! [drives off]
Wanda: Looks like we're going to the zoo and aquarium later.
Timmy: Okay, Poof! Change into a bird! [he shows Poof a picture of a bird. Poof giggles and turns into a rocket] He's getting better. [Poof blasts off] Birds and rockets both fly and have wings. [Poof lands in the Turners' front yard. Mr. and Mrs. Turner see the resulting crater]
Mrs. Turner: Was that an exploding bird? [Poof rises up in fairy form]
Mr. Turner: Yes. No! It's a baby! And he can float! [Poof burps, blowing the parents away]
Mrs. Turner: And he has a freakishly powerful gastrointestinal system!
Mr. Turner: Egads! [Timmy and Wanda appear nearby] We've been chosen to raise a floating, burping alien super baby!
Cosmo: Dah! Those two have no idea how to raise a child! No offense, Timmy.
Timmy: [wryly] None taken. Come on, let's go get your baby back. [cut to inside the house]
Mrs. Turner: A bouncing baby boy who really bounces! [bounces Poof to Mr. Turner]
Mr. Turner: Remember how we tried this with Timmy? He never bounced back.
Timmy: Hi, Mom! Hi, Dad! Whatchoo got there? Wow! A baby. Cool. [takes Poof] I'll just take him back and find his real parents. Bye!
Mr. Turner: [takes Poof back] But we're his parents now Timmy, meet your new super-powered brother!
Timmy: [wryly] Nice to meet you, super-powered baby that I've never met before.
Mrs. Turner: Oh, we should give him a name. Like... New Timmy! [puts Timmy's hat on Poof]
Mr. Turner: Or what about Better Timmy?
Timmy: What? Those are terrible names!
Mr. Turner: Ooh! Maybe Jealous Timmy is right. Then how about Super Baby? [Poof yawns] Uh-oh! I think it's nap time!
Mrs. Turner: I'll get the binky! [she puts pacifiers in her and Mr. Turner's mouths, and they fall asleep, as does Poof. Timmy zips away with Poof. In his room, Cosmo and Wanda appear in their fishbowl]
Timmy: Well, that was easy. Okay, Poof, just shape-shift into a fish so you can go back to your real parents. [Poof giggles and turns into a crab] Close enough. [he drops Poof over the bowl, but a magical barrier stops Poof. Timmy tries to throw him down]
Wanda: Hurry up, Timmy! We miss our baby!
Timmy: I'm trying, but he won't go in! [hears his parents crying] Don't cry, guys. I'll get him in.
Cosmo and Wanda: It's not us crying. [cut to Mr. and Mrs. Turner crying on the living room couch]
Mrs. Turner: Super Baby's gone!
Mr. Turner: [holding a photo of Poof] We loved Super Baby so much! Where'd we get this picture? [they continue crying, and Timmy and the fairies watch them]
Timmy: Okay. I wish my parents weren't sad and they forgot all about Poof! [Cosmo and Wanda raise their wands. Mr. and Mrs. Turner magically stop crying, but continue a moment later]
Cosmo: Oh, no! Your parents fell in love with Poof, and according to the rules, we can't unwish true love!
Timmy: But there's got to be a way to fix this mess and get Poof back to you!
Wanda: [reading Da Rules] The rules say we can get Poof back if your parents give him up willingly.
Timmy: Then that's what we'll make them do. I wish Poof was on the couch! [Cosmo and Wanda grant the wish. Mr. and Mrs. Turner see Poof and shout giddily]
Mr. Turner: Super Baby is back! Hooray! We can be parents again!
Mrs. Turner: That's why I made him this! [she holds up a superhero costume and Mr. Turner puts Poof in it]
Poof: Ta-da!
Mr. Turner: Now let's see if this baby can fly! [puts Poof in a baby carrier he is wearing] Why don't I just take you to the aquarium like I never took Timmy? [as Poof flies him away] Super Baby away!
Timmy: The aquarium? I asked him to take me there, like, a million times! I mean to the aquarium! [Wanda poofs them and Cosmo away. Fade to the Dimmsdale Aquarium. A sea lion dives into its tank]
Mr. Turner: [to Poof] And this is called a seal! [the sea lion points to a sign reading "Sea lion (not seal)"] Oh, excuse me, a seal with an attitude! [walks away]
Timmy: Hey, Dad, weird running into you here, huh? Hey, I think it's time for me and my new brother to bond.
Mr. Turner: I don't know, Jealous Timmy. Can you put your unbridled rage aside to care for your new super baby brother?
Timmy: You bet. I just want to show him some totally cool fish around the corner, so could you please willingly hand him over?
Mr. Turner: Sure, non-super son! [giving him Poof] Glad to see you embracing your super sibling! [Poof giggles as Timmy takes him to a tank with Cosmo and Wanda as goldfish in it]
Cosmo and Wanda: Poof! We missed you so!
Timmy: Okay, Poof, shape-shift into your little goldfish self. I'll tell Dad that you took off for outer space in search of your real—
Mark: [in the tank] Turner! You gotta get me outta here, bro, and, like, fix my Fake-I-Fier, yo! [he spins the Fake-I-Fier's dial, and it breaks. A female octopus hugs him tightly] I told you I'm not that into you.
Poof: Fishy!
Cosmo, Timmy, and Wanda: No! No, Poof! No! No! / No, no fishy! / No! No, Poof! No! [Poof giggles and turns into a giant octopus. People run away screaming. Poof starts climbing into a tank, making the sharks in it swim away]
Timmy: [gets on Poof] Poof, no! You're not an octopus! You're a baby! A cute baby! [Poof turns back to normal. Timmy catches him]
Mr. Turner: [shouts] Timmy! [Timmy is holding Poof over the shark tank]
Timmy: This looks bad, right? [fade to him on his bed]
Mr. Turner: Stay here, away from your awesome brother, and think about why you can't treat him like shark food.
Mrs. Turner: And speaking of food, time to go shopping! But where do we buy food for a super baby?
Mr. and Mrs. Turner: At the supermarket! Jinx! [they leave]
Cosmo and Wanda: Tell us you have a new plan!
Timmy: Oh, yeah. [fade to Mrs. Turner and Poof in a supermarket. Cosmo and Wanda spy on them as cereal boxes] Poof's really getting his shape-shifting down, so all we got to do is get him to shapeshift into something that'll really scare the heck outta my mom. Then she'll willingly give up Poof!
Cosmo: Good plan!
Timmy: I wish this aisle was full of boxes of super fortified terrifying Monster O's! [Cosmo and Wanda grant the wish]
Poof: [coos] Monster!
Mrs. Turner: Ooh, you want cereal? Well, let's see if there are any harmful ingredients. [behind her, Poof turns into an O-shaped monster and roars]
Wanda: [to Timmy] Perfect! When your mom sees this, she'll definitely give up Poof! [people scream]
Poof: Huh? [walks toward the people and roars]
Mrs. Turner: [looking at the back of a Monster O's box] Let's see. Sugar, fangs, venom...
Timmy: Mom! [Poof chases people past him] Mom! [again]Mom!
Voice on PA System: [as Poof knocks down a shelf behind Mrs. Turner] Uh, gruesome monster clean-up, aisle three.
Timmy: [as Poof approaches him from behind] Hello? Look behind you!
Cosmo and Wanda: Timmy!
Timmy: What?
Cosmo and Wanda: Look behind you! [once Timmy does so, they all scream and zip away. Poof laughs and starts chasing them]
Cosmo: Hey! I think he's coming to give us a hug! [Poof knocks him into the fresh produce aisle. He spits out a carrot] Or not.
Wanda: Timmy, we got to stop Poof! [Timmy grabs balloons and uses them to float toward Poof]
Timmy: Poof! Stop! You're going to hurt someone! [Poof trips on a shopping cart] Possibly me! [Poof falls on him and rolls into the deli counter. Poof turns back to normal, and Timmy lands on the counter and catches him. Mrs. Turner sees them and screams, having noticed the meat slicer beside them. Timmy moves Poof away from it, and his mother glares at him] Man, I can't win today! [fade to him being put in a cage in his room. Chains are put around it]
Mr. Turner: I know it's hard accepting a new member to the family but come on! A deli slicer?
Mrs. Turner: Now, I don't want to see you trying to thinly slice your brother again!
Timmy: But, but...
Mr. Turner: No buts! We are through entertaining your company! [Mr. Turner refused to listen and puts padlocks on the cage and the chains. Fade to a playground. A baby takes Poof's rattle. The two tug on it, and Poof flings the baby screaming into a bush, making the baby's mother scream]
Mrs. Turner: It's okay. He's a super baby from outer space sent to protect us! [Timmy, Wanda, and Cosmo are watching from behind a tree]
Wanda: Okay, Timmy. We've been very patient, but we want our baby back!
Timmy: I'm sorry, Wanda. My parents won't listen to me! I know if my mom could see she's breaking another mother's heart, she'd give up Poof.
Cosmo: But she thinks he's an alien! Where are we going to find an alien mother that your parents will willingly give Poof back to? [behind him, Mark has come out of a sewer]
Mark: Turner! I have es-caped from the fish prison! Can you please fix my Fake-I-Fier? I will do anything you ask if you will only, like, help me, okay? [Timmy and the godparents smile smugly] What's with the creepy smiles? [cut to him ringing the Turners' doorbell. Mr. and Mrs. Turner open the door and recoil. Mark is dressed as a human woman] Uh, okay. Greetings, earthlings. Please help mend a mother's broken heart [he is reading from cue cards held up by Timmy, who is beside the door] and return my most precious alien baby.
Cosmo: [to Timmy] Wow, he's really good!
Mrs. Turner: Oh. Are you Super Baby's mother?
Timmy: [to Mark, pointing to a cue card] Ahem!
Mark: Oh, yeah. And a very distraught mother at that. [to Poof] Come home with me, my little baby!
Mrs. Turner: Oh, honey, we have no choice! We must give Super Baby to his hideous real mother!
Mr. Turner: It's the right thing to do.
Mark: [takes Poof] All right! [Poof giggles and changes himself to look like him] Cool! Laters! [he boards his spaceship, which has a sticker reading "Alien baby on board" on it and blasts off. He lands in the backyard and comes out with Poof. Timmy, Cosmo, and Wanda appear]
Wanda: Ooh, our baby! We have our baby back!
Cosmo: [sniffs] Someone needs a diaper change! And it isn't me this time!
Timmy: Now I wish Mark's Fake-I-Fier was repaired! [the wish is granted. Mark uses the Fake-I-Fier to turn into Justin Jake Ashton]
Wanda: Oh, Mark—I mean, Justin Jake Ashton—is there anything we can do for you?
Mark: I'll take that diaper... to go! [she gives him Poof's diaper, and he smells it] Ha.
Timmy: Okay, time to repair my mom and dad's broken hearts. [fade to night. Mr. and Mrs. Turner are looking into the sky] So, Super Baby's gone, huh?
Mr. Turner: He's where he needs to be. With his real mom and dad.
Mrs. Turner: [putting Timmy's hat on Timmy] I guess this mom and dad will have to settle for just one super son.
Timmy: You guys think I'm super?
Mr. and Mrs. Turner: Oh, ho ho ho! / Oh, ho ho!
Mr. Turner: The superest! Which means you'll need a super outfit if you're going to fight crime!
Mrs. Turner: So, I made you something that will go with those super teeth of yours! [puts him in a beaver costume]
Mr. Turner: I hereby dub thee Beaver Boy! Nobody takes a bigger bite out of crime!
Timmy: Awesome! I'm a super son and a superhero! [someone in a bush shoots him with a tranquilizer dart, making him fall asleep]
Game Hunter: [coming out of the bush] Blimey! A giant beaver! Good hunting' in these parts there is!
Mr. Turner: Look, honey! It must be nap time! [he and Mrs. Turner put pacifiers in their mouths and fall asleep. The scene begins to iris out, but Mark grabs the iris]
Mark: Diapers rock! [chuckles. Iris out. The end title card is shown. Fade to black]
