Spa Day

It's not "fun", its relaxing! Which makes it enjoyable! Which makes it fun! Grown-up fun! You wouldn't understand.

Candace and Stacy have a spa day. But thanks to Candace, they get sidetracked when she noticed that Jeremy was building houses and decides that she and Stacy should help them. Their spa day also inspired Phineas and Ferb to build a spa of their own. Meanwhile Doofenshmirtz takes in a lost kitten that causes havoc with his old inventions.

Episode Summary
Candace and Stacy are getting ready for their first spa day together. Phineas likes the idea and looks through the pamphlet, but Candace tells him that you can't get in this spa unless you know someone, and she knows Stacy who has connections of her own with someone who works there. Once they leave, Phineas and Ferb decide to start a spa of their own with help from their friends. Meanwhile, Dr. Doofenshmirtz checks his mail and sees a stray black and white cat which he decides to name Mr. Fluffypants, as he's fluffy, looks like he's wearing pants, and reminds him of his Uncle Fluffypants.

While Phineas, Ferb and their friends set up the spa in their backyard, Candace and Stacy head to their spa appointment. They get sidetracked when Jeremy tells the girls he's building houses for the homeless. Although Stacy tells Candace they should just go to the spa, and Jeremy doesn't mind her not helping him out, she insists on trying to impress him. Back at Doofenshmirtz's, the cat he took in is causing all sorts of trouble, ripping up blueprints and firing his laser cannons on accident. At one point, the Gloominator is fired into the air and is causes the sky to turn gloomy. Major Monogram sends Perry to stop him, especially since they thought that he had retired the Gloominator months ago.

Candace tells Stacy that after they quickly help Jeremy out, they can go to the spa. However, Candace gets so distracted by Jeremy that Stacy gets frequently injured in the process. Jeremy finishes his part of the house and leaves, and Stacy almost leaves for the spa without Candace, but their boss hands her a jackhammer and tells them to turn the concrete into rubble by sundown before they leave. Candace accidentally turns on the jackhammer, which goes out of control with Stacy on it. Perry makes his way to Doofenshmirtz's lair, and he tries to tell Perry it was the cat messing around with his equipment. Perry doesn't believe him and attacks him.

The two girls walk home exhausted, and Candace apologizes to Stacy for everything, mainly missing their spa appointment. But Stacy tells her it's okay because she did it for love, and reminds her of the time she put a hamster in Candace's hair in the 3rd grade to impress a boy named Billy Clark. When they arrive home, they see that Phineas and Ferb built their own professional spa in the backyard. Candace wants to bust them at first, but Stacy glares at her angrily and decide to use it their advantage instead. They are soon pampered with help from Isabella and the Fireside Girls. As they are their last two customers, Phineas and Ferb decide to close up the spa, but they're free to stay here as long as they want.

Perry finally realizes Doofenshmirtz was telling the truth when he sees the cat is messing around on top of a ray gun, firing it. The ray causes to spa to disappear, leaving only Candace and Stacy lying in the backyard in towels and cucumber slices on their eyes. The cat almost falls off the ray, but Doofenshmirtz saves him, only to fall over the side of the building. Perry saves the two and safely floats down via a parachute. A boy soon shows up looking for his lost cat, and knowing he has to do the right thing, Doofenshmirtz groans and returns the cat to his owner. Everyone is moved except Doofenshmirtz, who asks everyone "Don't you people have jobs?"

Errors

 * In the early part of the song, Stacy's bow was purple.
 * During the song, it looks like Ginger is walking on Stacy's head when the Fireside Girls were walking on Candace's and Stacy's backs.

Continuity

 * The Gloominator 3000-inator, The Media Erasinator, and Inator appear in this episode. ("Leave the Busting to Us!", "Voyage to the Bottom of Buford", and "Unfair Science Fair Redux (Another Story)") . Also, the Bigger-inator might be based on the fact that his Smell-inator accidentally made the Universe 10 times bigger because of a growth potion. ("Attack of the 50 Foot Sister")
 * The Giant Squid that Buford fought for the seaweed makes a return appearance. ("Voyage to the Bottom of Buford")
 * Candace still wants to name her children Xavier and Amanda. ("The Best Lazy Day Ever", "Swiss Family Phineas")
 * Doofenshmirtz said "Ha, ha, I'm painting!" the same way Lawrence did in "It's a Mud, Mud, Mud, Mud World".
 * The man who thinks Phineas is young used to work in the company "Love on the Run", while the other delivery dude who completes the Too Young Line is the same guy from the Haunted House. ("Dude, We're Getting the Band Back Together", "One Good Scare Ought to Do It!")
 * Doofenshmirtz said "I'm going to have to do the right thing here, aren't I?" just like Candace at the end of "The Lake Nose Monster". The crowd around him goes "Aww," just like they did when he saved the kitten in "Voyage to the Bottom of Buford".
 * While the Fireside Girls (Holly, Isabella, and Ginger) were walking on their spines, you can see Candace and Stacy wearing the swimsuits that they wore at Jeremy's pool party. ("De Plane! De Plane!")
 * The kid who lost his cat was the same kid who was behind Doofenshmirtz at the public pool in "Split Personality", but he has a different voice.
 * This is the third time that someone (in this case Candace and Stacy) goes to a spa. The first time were Linda and Charlene ("Lawn Gnome Beach Party of Terror") and ("Hail Doofania!")

Allusions

 * That's So Raven: Candace is distracted by Jeremy and accidentally glues Stacy to the wall, similar to what Chelsea did to Raven in the episode "Hook Up My Space".
 * The Simpsons: When Doofenshmirtz is painted he looks like Krusty the Clown.
 * Pinocchio/Pluto's Judgement Day: Mr. Fluffypants (a.k.a. Mr. Cat) parallels resemblances to Figaro from the movie & (the bottom "pants") and the kitten from the cartoon short (the top).
 * Thomas the Tank Engine: In the song "Spa Day" the whistling kettle when slowed down, is the same whistle as Thomas the Tank Engine's.
 * Hot Rod: When Jeremy thinks that Candace and Stacy is doing fine he says "Cool Beans", to which Candace replies "Yeah! Cool Beans". This is a reference to the 2007 The Lonely Island feature film.
