Phineas and Ferb: Summer Belongs To You!

Phineas feels bored after he and Ferb have accomplished much throughout the summer. For a taste of adventure, the duo and their friends decide to travel around the world at the same speed as the Earth's rotation, so as to make a complete 24-hour day, in an effort to create the "biggest, longest, funnest summer day of all time".

Meanwhile, Dr. Doofenshmirtz takes a trip to Tokyo with Vanessa. At first, Vanessa is amazed, but is later distraught to find out that her father has brought in a captured Major Monogram and has been making a plan to ruin the International Good Guy Convention with a giant water balloon and frame Monogram for it. She then accuses her father of always putting his work before her relationship with him, and decides to leave for Paris on her own. Around the same time, Perry the Platypus catches wind of Monogram's whereabouts after Carl warns him of a suspicious note sent to the O.W.C.A. (presumably sent by Doofenshmirtz).

In Tokyo, the gang meets with Stacy's cousins while getting vegetable oil used as fuel. While there, Vanessa joins with the group after being accidentally knocked off the Tokyo Tower by the giant balloon thanks to the intervention of Perry, who arrives at the tower as Agent P. Fearing for Vanessa's safety, Doof decides to abandon his plan and opts to rescue her, and Perry and Major Monogram are compelled to help him, so they travel aboard Agent P's platypus-shaped hovercar.

The group, along with Vanessa, then crashes on the Indian portion of the Himalayas, and their plane loses its wings. Phineas and the other kids go see Baljeet's uncle Sabu, who runs a rubber band/rubber ball factory there. He sings "Rubber Bands" as he shows the kids around the factory. This gives them an idea: namely, to attach a bouncy rubber ball to the bottom of the plane so they could travel their way to Paris and back home. As they travel around the world in their newly-fixed way of transport, we hear the song "Bouncin' Around The World".

In Paris, known to Isabella as "the city of love", Candace sees Jeremy with a bunch of boys and girls and leaves. Isabella is upset as Phineas is completely oblivious to her feelings for him, since what he cares about the most is getting the craft refixed. On the top of the Eiffel Tower, Ferb consults with a depressed Vanessa about her relationship with her father, telling her to try and meet him halfway in their relationship by socializing more. Ferb walks away for a moment; then Doofenshmirtz, Perry, and Major Monogram come to rescue her. Vanessa is initially upset at her father bringing 'work' again, but Doof complains of all the trouble and the help he needed from Perry and Monogram to travel halfway around the world to rescue Vanessa for her sake.

The group later crashes on a deserted island, which possesses only two palm trees and a big fat ox. The boat disintegrates leaving only the seats. Meanwhile, in Paris, Major Monogram and Perry arrest Doof, along with Vanessa, who stops them and goes away with her father in Perry's hovercraft. This leaves the platypus upset as he is left behind by Monogram, who has to "take in a review". Back on the isle, Phineas, after a desperate attempt to find a way (even finding a sponge and a starfish under the sand), finally gives up and sits down to watch the sunset with Isabella like she wants, but she encourages him and he gets the idea to use Ferb's giant map as a massive paper airplane. With 1 minute left, Buford gives everyone back their bikes and the group is able to jump the pit using a makeshift ramp and arrive home with a second to spare. The parents arrive home too, but for once Candace says nothing as she enjoyed herself. As everyone sings "Summer Belongs to You", Jeremy comes home early and kisses Candace, calling her his girlfriend to her excitement. After the celebration, Phineas wonders where Perry might be, and the episode ends with the abandoned platypus at a fancy restaurant in Paris, presumably in an attempt to cheer himself up.

During the song, "City of Love", Phineas can briefly be seen standing in front of the famous French Cabaret, Moulin Rouge while holding a pinwheel, most likely envisioning the use of the windmill on top as a propeller. This episode also pays homage to the popular Japanese dance tone "Caramelldansen" in which Stacy's relatives encourage Phineas and Ferb to participate in a dance and tune similar to the smash hit. Also in one part of the song, Isabella is seen waving a leek in her hand, similarly to Loituma Girl in the popular video known as "Leekspin" on YouTube.[1] Phineas is also seen digging up a yellow sponge and a pink starfish in the episode, as a reference to SpongeBob SquarePants.
