Attack of the Turbo Tibbles/Muffy Goes Metropolitan
Ms. Morgan's preschool class are on a field trip at Lakewood Elementary School, where Arthur goes to school, for Project Day. D.W. walks to the table where Arthur and his friends are sitting at, and she asks if she can sit with them, but Arthur refuses and says she's supposed to sit with the preschoolers. Arthur then overhears D.W. telling everyone that he continued having nightmares about his underwear to embarrass him more, and then she pulls out a pair of sky blue boxer shorts with rabbits on them, and everyone starts laughing, much to his embarrassment.
After lunch, Mr. Ratburn tells his students that they should get ready to know their preschool buddies, listen to what they do, and present the project to the entire school. Binky is paired with D.W. Arthur and Buster are paired with the Tibbles. Binky asks D.W. what she's interested in, and she tells him she is interested in unicorns. Binky asks D.W. if she also likes professional wrestling, to which she answers that she likes ponies. Binky continues by asking her if she likes Harold the Head Masher, to which she answers that she likes "ponies with pretty manes you can brush." Finally, Binky asks D.W. if she likes Brutus the Bone Crusher, to which she answers that she likes rainbows. Binky then asks Mr. Ratburn if he may trade partners, and Mr. Ratburn says no by shaking his head.
At the Reads' house, D.W. asks for a play, but Binky refuses. They see an advertisement for a dance show called Thunderdance on TV and decide to do something like it. However, D.W. doesn't know how to dance. Then D.W. changes into her striped gymnastics suit and Binky brings in a stereo player. Binky then starts playing music and shows D.W. some dance moves. D.W. then attempts to do what he showed her, but she ends up falling backwards. Outside, Binky's friends Molly and Rattles are walking Rattles' dog and see him inside at the Reads' teaching D.W. how to dance. Back in the house, Binky shows D.W a Grand Jeté move. D.W. attempts to do the same thing, but Binky points out she is making mistakes, and then stops playing the music.
The next day, Binky arrives at the Reads' wearing a suit and tie, and explains that it's what teachers wear. He suggests that D.W. should refer to him as "Mr. Barnes" (not to be confused with his father with an unknown given name), and D.W. retaliates the suggestion by saying he has a screw loose.
The next day, Binky then shows D.W. a video on television about a dancer named Gene Kelpie who is doing dance moves on his toes on one foot, raising his leg, carrying a mop, and spinning in circles. After showing D.W., he rewinds the cassette, then D.W. copies the dance move and accidentally breaks her family's most favorite standing lamp that always sat in the living room. Binky then hands D.W. a stack of index cards that tell her to copy the dance movies, and tells her that there will be an upcoming exam.
The next day, Binky shows D.W. how to tap-dance. D.W. attempts to do it, but only taps once, and Binky is unhappy she didn't try hard enough, and D.W. blames it on the sneakers that are sticking to the floor. Binky asks D.W. if she learned anything from the index cards, to which she admits that she didn't because she can't read, since she's four years old. Binky then grades D.W. a C, but D.W. doesn't care and suggests another project. D.W. admits she is not doing very well, but Binky claims he is trying his best to teach her.
As Binky leaves the Reads' house, his friends call him "twinkle toes" and start making fun of him. They think D.W.'s a baby and Binky lies to them saying that he's teaching D.W. fighting moves. Rattles then looks through the cards that Binky wrote to teach D.W. and believes Binky, since the names of the dance moves he was teaching D.W. sound like fighting moves. Molly and Rattles wish that Binky would teach them those martial arts moves as well.
On the Lakewood Elementary School playground, Binky starts teaching Rattles and Molly some dancing moves, but he points out they're making mistakes like D.W. did earlier. Molly and Rattles claim the reason they're making mistakes is that Binky is going too quickly and using words they don't understand. Binky is surprised to hear this, as he thought everybody knew the names and the moves. Molly explains it might be easy for Binky, but it's new to D.W and the rest of them. Rattles and Molly want Binky to take things slow so they don't mess up and request he be more encouraging. Binky then accepts the blame for being a lousy dance teacher and leaves.
Back at the Reads' house, Binky then shows D.W. dancing moves in her and Kate's room like he tried earlier. D.W. then applauds to him and then walks up to him. Back on the playground, Binky starts playing some exciting music and teaches Rattles and Molly some more dance moves. Rattles takes an attempt, but then falls down, but Binky thumbs up his performance. Back at the Reads' house, Binky starts playing with D.W.'s toy unicorns, and she applauds. Outside, they dance together. Out by the trees, Binky then leads Rattles and Molly going across a dirt footpath doing dance moves. Then they walk across a see-saw.
At the Reads' house, D.W. dances in circles, but Binky suggests that D.W. keep her eyes fixed on one spot to keep herself from getting dizzy. Then Binky spins on the living room rug, causing it to twirl, and then he falls down, having twisted his ankle. D.W. warns him that the project is the next day.
On the day of the project, it's all being presented in the Lakewood Elementary School auditorium. The Tibble twins, who play the monster trucks, bump into their partners, Arthur and Buster. The Tibble twins then get up out of their monster truck costumes and bow to the entire crowd. Arthur and Buster feel the pain from what happened in their project and leave. Binky, who has his foot in a brace, tells D.W., who is dressed for the concert, to remember what they practiced, and hopes she'll do fine. Binky starts playing the music, and D.W. goes up in the spotlight and dances. Rattles and Molly join in with D.W.
After the concert, Mr. Ratburn congratulates Binky and Rattles. Then Binky hands Rattles and Molly their black belts. He then gives D.W. a pair of his old ballet slippers as a present. D.W. thanks him, but admits they are too large for her. Binky suggests that she'll grow into them. As Binky leaves, D.W. tries on the slippers, but starts losing her balance.
During lunch, the third-graders discuss their plans for the three-day weekend ahead of them. Sue Ellen’s dad is taking her to Crown City where they will stay with Sue Ellen’s old sitter, Carla. The other kids all speak fondly of Crown City, but Muffy seems sad.
In art class, Muffy keeps talking about Crown City to Sue Ellen. Sue Ellen guesses that Muffy has never actually been there and somewhat reluctantly invites her to come.
When Mr. Armstrong and Sue Ellen pick her up, Muffy shows them a to-do list including a fancy dinner, a shopping spree, and a cultural event.
Muffy is disappointed that Carla lives in a fairly poor part of town. They go to eat in an Ethiopian restaurant where Muffy is horrified that people eat with their hands and there is only one waiter. Sue Ellen promises they will go shopping the next day.
They go shopping at an open-air market and in a cheap boutique, where Carla shows Muffy a cowskin beret that Muffy calls “passé” but buys anyway. They buy lunch at a hot dog stand where Carla announces that they will go to René's that night.
Muffy images René's as a modern art gallery where she meets Andy Warthog and Keith Herring. As it turns out, René's is a small club where a poetry slam is going on. After sitting on old gum, Muffy gripes loudly about Crown City in the manner of a free-style poem. The audience applauds.
When Carla and the girls enter a subway station, Muffy is heartbroken. She cheers up when she notices how pretty the old station is. There are jazz musicians and a pretzel stand. Muffy sees a poster for a Moonlight Lantern Parade and Carla offers to take the girls there. Muffy puts on the cowskin beret and goes to buy a pretzel.
In the end, they come out of another subway station singing the Crown City song.
