Episode Summary
Linda is trying to set up a block party, and she tells the boys that she is overwhelmed with all the work she has to do. Phineas and Ferb think of ideas for the party finale, and they decide on a laser light show. Linda then gives them a list of companies that do light shows, but Phineas decides that they should just build it themselves instead. Lawrence then arrives dressed up as a Mardi Gras jester, or a "sock puppet" as most think; he explains that he is the DJ for the block party, and wonders where Perry is. Major Monogram informs Perry about his mission, which involves the block party. He states that Doofenshmirtz is attending the party, reportedly "for the fun of it", and Agent P has to make sure that he isn't doing evil. However, he has to be in disguise because he is so close to his host family, and ends up dressing as a balloon version of himself.

Candace, in her room, wants to bust the boys, but they haven't done anything bustable all day. However, Stacy promptly points out a robotic insect that Phineas and Ferb have made. Candace immediately goes out and asks Phineas what they're doing, and he explains that they are making the laser light show for the finale. Candace heads straight into the house after learning about their project and yells for Linda. At Doofenshmirtz Evil Incorporated, Doof and Norm have plans to go to the block party, but Norm doesn't want to go because he doesn't have a date. Doof gives Norm advice to go stag, clarifying that he does not mean for Norm to dress as a wild forest animal. Norm is still disappointed, but Doof tells him that he might meet a nice popcorn machine or blender. Norm then agrees to go.

Phineas and Ferb show Isabella, Buford, and Baljeet the "Phlaser", the machine that will create the laser light show for the party. While Phineas goes to get some towels to polish the lenses, Candace sits in a lawn chair, muttering to herself how the situation is "unbustable". Stacy then drags Candace away. Perry, still in disguise, bounces across some port-a-potties and lands in a balloon booth, where he starts to spy on Doofenshmirtz.

Doof is helping Norm be smooth in order to ask out a popcorn machine, but a cotton candy cart rolls up, and Doof says that someone else has gotten her. Norm sighs, but then lights up when he sees a female robot, Chloe, through the crowd. Doof realizes that Norm has his eye on her and convinces Norm to make his move by asking what her sign is. He goes up to introduce himself, but upon Chloe's response (Pisces), returns to Doof as he doesn't know what to say next. Doof reveals that Charlene was a Pisces, and remarks that the two robots could well end up marrying and then slowly divorcing over the years. He then tell Norm what to do next. Balthazar Horowitz walks up to Perry but Perry shushes him and makes him a balloon fedora so he can keep his cover. Major Monogram contacts Perry over the wrist beacon but Perry notices that Major Monogram is right behind him with an ice cream cone. Major Monogram awkwardly signs off and yells at Carl for not telling him that Agent P was right there.

Norm walks up to Chloe and after an awkward conversation ends up challenging her to a dance off. He walks back to Doof and Doof tells Norm to try to get out of his own head, Norm isn't sure how to do that and Doof pushes Norm out to the dance floor.

Up on stage, Lawrence turns on the music and Norm and Chloe dance. At the end of the song, Norm's head flies off and lands on the Phlaser, shorting it out and activating the grand finale prematurely. Isabella and the Fireside Girls hand out safety glasses to protect people from the light. A stream of multi-color light streams come out of the exploding Phlaser as the crowd stares in awe. The show ends and Norm's head falls back on to his body, upside-down.

Norm and Chloe hold hands and Doof arrives to congratulate Norm for being "Smoothtastic". Rodney suddenly appears and pulls Chloe away from Norm for hanging out with that "Rustbed Romeo". Doof tries to yell back at Rodney, but can't think of an insult. Norm and Chloe say their goodbyes, quoting Romeo and Juliet, and Doof tells Norm that he didn't need Chloe anyway.

Linda comes to thank the boys, but then "busts" them for leaving her guest towels dirty and all over the ground. Candace complains that out of all the things Phineas and Ferb have done this summer, she is upset about this. Linda then tells the boys to clean up and goes to make dinner, leaving Candace frustrated.
