No More Bunny Business

Candace finds a bunny outside of her house and decides to take care of it. However, the bunny is actually Dennis; a former O.W.C.A. agent who went rogue and is on a mission to infiltrate Perry's lair and steal the system of the O.W.C.A. Meanwhile, Phineas and Ferb build X-Ray Glasses after purchasing some and being ripped off. The glasses then help them help others. Elsewhere, after realizing that Perry the Platypus isn't showing up, Dr. Doofenshmirtz decides to create his own substitute nemesis instead of Perry. His plan was to induce all of the dogs in the apartment next to his building away so that he wouldn't be annoyed by the noise they make.

Episode Summary
Phineas and Ferb are camping out in the mailbox, waiting for a package. When the mail lady comes by, Phineas pops out of the mailbox, spooking her, asking if the package came. She apologizes and tells them that it hasn't come. As the boys come out of the mailbox, the mail lady hands them the mail, then walks off. She then comes back, saying that she forgot something (a magazine for Linda). The boys are instantly back beside the mailbox, hoping for their package, but then the mail lady hands them their mom's magazine. Bummed, they walk back to the house, believing it hasn't come but Candace starts nagging them moving a "stupid box out of the doorway". as Candace tells them it came while they were camping out in the mailbox, Phineas zips over to the box and tears it open, tossing out tons of packing peanuts, which Ferb catches in a trashbag. He takes an even smaller box out from the original box and from that box he pulls a pair of X-Ray glasses they had ordered from a comic. Phineas puts on the glasses, hoping to see the bones inside his hands, but only sees swirls and an outline of his hand. He re-reads the ad in the comic, and reads that the glasses don't actually provide X-Ray vision. Disappointed, he calls the glasses a rip-off, "just like the body building course they got last summer", but Ferb does a pose behind his back, exposing muscles that he had earned from that same body building course (Phineas doesn't see). Ferb, looking normal again, puts on the glasses himself, which inspires Phineas to make real X-Ray glasses.

When Candace is going back in the house, she finds an adorable rabbit and takes it in, cooing that she was going to take good care of it and that it was so cute. Meanwhile, Perry is shown at his lair, where Major Monogram informs him although Doofenshmirtz is "up to his usual shenanigans", they had a more serious problem about a rogue agent in Perry's area. Carl comes up with a primitive sketch of a rabbit, but is turned away by Monogram, who berates Carl for saying he could draw. Carl walks offscreen, and Monogram tells Perry to look out for any suspicious characters, because the rogue agent may try to infiltrate Perry's lair to hack into the Agency's mainframe. Perry gets his binoculars and searches for the rabbit from atop the chimney, but is spotted by Phineas and Ferb.

Phineas and Ferb are down on the ground and see that Perry is up on the roof with a pair of binoculars. As Perry is in his pet mode, they think nothing of it, with Phineas saying that "If he got himself up there, he can get himself down". They continue with their project, which seems to be going along well; they have the frames and lens solution for their X-ray vision glasses, so now all they need is a solution that improves eyesight. Ferb pulls out a blackboard with a drawing of a carrot on it.

Back on the roof, Agent P's wristwatch communicator beeps and Monogram appears on its little screen. He says that they had hired a professional artist, with much better results. He proceeds to display a number of pictures of a rabbit in various disguises, including that of the bunny Candace now has. Monogram tells Perry that this is Dennis and he is a mercenary for hire, then sends Perry out to stop him. He goes down the chimney and sneaks over to Candace's room.

Candace is looking for clothes to put on her rabbit, which she has named "Mr. Cutie Batutie". She says that she'll first give him a makeover and then teach him some cool tricks. When she turns away from him and digs through a chest full of dress-up clothes, Dennis stands upright and pulls out a map of the Flynn-Fletcher house. He starts going around her room and searching for an entrance to Perry's lair. Perry marches in and confronts Dennis. When they growl at eachother, Candace turns around, sees Perry, and pushes him out of her room, saying that she "doesn't want his blandness to rub off". She then gives Dennis his makeover, putting him in a purple dress with matching shoes. Dennis sees Agent P outside the window, signaling him that he'd be watching his every move, and hastily pulls the curtains closed just as Candace is walking up.

At Doofenshmirtz Evil Inc., Doofenshmirtz is getting tired of waiting for Agent P to show up. He starts reciting his evil monologue from a script, then decides he doesn't need Agent P, so he puts a paper fedora on a potted plant and ties it up in a trap as though it were Agent P.

Phineas and Ferb head to the kitchen for some carrots. They open the refrigerator and pull out one of the drawers, but just as they are about to grab a large bunch of carrots, Candace snatches them away. Phineas tries to explain to her that they need them. Candace then says "Oh really? For your stupid X-Ray glasses?". Phineas, offended by Candace's comment, then tries to tell her that they aren't stupid, but is cut off again by Candace telling him that Dennis (or, as she calls him, Mr. Cutie Batutie) is more important. Ferb asks why he is wearing a tutu, and Candace says, "He likes it!" She goes off to teach Dennis tricks. Phineas smirks and says maybe they can get carrots from Isabella.

Candace gives Dennis carrots to teach him tricks. She somehow does not think it to be at all odd that the rabbit knows the Worm and the Robot. She runs off and Dennis resumes his investigation for lair entrances. When he tries to get in through the clock, Perry pops out and kicks him away. Perry and Dennis charge at eachother and start wrestling, but have to stop and revert to "mindless domestic animal mode" when Linda walks by and almost sees their fight to the death. She leaves, saying "Oh. A bunny rabbit, Candace must have gotten a new pet." The animals both stare at each other, then Perry chatters and Dennis growls, and they begin fighting again. They seem to be matched in hand-to-hand combat, blocking and countering eachother's blows. Dennis leaps up onto a table to take the advantage of being up higher and throws a lamp at Perry. Perry catches it and replaces it onto the table as he pursues Dennis into the kitchen and out the door.

Meanwhile, Doofenshmirtz is explaining his scheme to Planty the Potted Plant. He hears barking and meowing from next door and gets irritated, saying that ever since the condos next door started allowing pets, he has been going completely bonkers because the barking never ceases. And so, he has created the Dog-Biscuit-inator, which appears to be a giant dog bone attached to rockets. He explains how he will cover the bone with "an irresistible gravy coating" and launch the bone out of the Tri-State Area so that all the dogs will follow it. He finishes his monologue with a smug remark, then pushes Planty the Potted Plant away, saying, "Don't give me that look." As he prepares to launch the bone, the suspended plant swings back and forth, hitting him in the head time and time again.

After obtaining their carrots, the boys make carrot juice, putting it through a machine to make it super-concentrated.As Ferb stomps on the carrots, Phineas dips the lenses into the solution and says they need to wait a couple of hours for it to set properly. Isabella tells him they could do that, or they could get it done in 5 minutes in her Quick-E-Bake Oven. She takes the glasses from him and puts them in her oven (which is for some reason sitting in the Flynn-Fletcher backyard), saying that Fireside Girls are always prepared. 5 minutes later, Isabella taps on the lenses and proclaims them ready. They prepare to try them out and are interrupted by a heart-rending wail, which Isabella says sounds like it's coming from her own house. They rush over and discover that Mrs. Garcia-Shapiro had lost her wedding ring. Phineas uses the X-ray glasses and finds it in the drain, then calls for Ferb to get a 14-inch pipe wrench, a blowtorch, and a jar of mayonnaise. Ferb disappears and reappears with the requested items, but Mrs. Garcia-Shapiro turns down their offer, saying that their regular plumber could take it from here. Phineas and Ferb proceed to help citizens all over Danville find things with their X-Ray goggles. They finish their quality-control tests and start to mass-produce the glasses, so Phineas orders a "big old truckload of carrots" and they run off, leaving the glasses on the table in the backyard.

While Candace looks for Dennis inside, Perry and Dennis are still fighting outside. They battle eachother with grilling equipment as though in a sword fight. Perry overpowers Dennis with one hand behind his back and thinks he has him defeated, but Dennis kicks Perry into a bra or swimsuit top hanging from the clothesline and uses Phineas and Ferb's glasses to look for a lair opening. Succeeding in finding one, he pulls away the grass covering it and jumps in. Perry untangles himself from the undergarment and follows. He lands inside, but Dennis traps him and steals his hat right off of his head, which infuriates Perry. Dennis goes and sits in Perry's chair and the computer scans the hat, giving Dennis access to the Agency's mainframe. Major Monogram appears on the screen just before Dennis gets into the mainframe; he tells Perry that he has to stop him.

Phineas and Ferb have ordered the carrots. The truck comes and dumps them all in the backyard as Candace walks up and asks Phineas if he's seen Mr. Cutie Batutie. Phineas suggests that she check the backyard, then changes his mind when he sees all the carrots out there. They decide to go check the kitchen and run off.

Back at Doofenshmirtz Evil Inc., Doofenshmirtz is standing in the middle of his apartment with Planty the Potted Plant still suspended on a rope from the ceiling. His apartment is a wreck and the doctor himself doesn't look too good. Doofenshmirtz surrenders and sits down against a door, but is flattened when a horde of dogs bursts in because they smelled the bone and want to eat it. He says, "Curse you, Planty the Potted Plant!"

Back at the Flynn-Fletchers, a carrot falls into the hole for Perry's lair. Dennis smells it and goes to eat it. Perry sees all the carrots that are in the backyard on the screen and gets an idea. He pulls at a nearby lever with his tail, making a hole open in the backyard, letting all the carrots pour in. Dennis goes mad over the carrots and is distracted from Perry, who grabs a carrot and pushes a release button with it. He runs over and slaps a pair off handcuffs onto Dennis, who is lumpy and bloated with the amount of carrots he consumed. Perry snatches his hat back indignantly and Major Monogram congratulates him on defeating Dennis.

Candace and Phineas can't find Dennis and walk out into the backyard. Phineas discovers the disappeared carrots and is surprised that so many carrots would disappear after only a few seconds. He says "One minute there's a backyard full of carrots, I turn around for half a minute, and- Poof! - they're gone!" Candace says "Welcome to my world." and Phineas gets a glimpse of what Candace goes through almost every day. Perry shows up, and Candace is happy that he, at least, is still around. Candace then asks Perry if he likes pink, making Perry chatter nervously.

The episode ends with Carl and Monogram congratulating and welcoming Planty the Potted Plant to the Agency for stopping Doofenshmirtz when Perry was busy.
