Angelina, Vici and Gracie need to get ready for a big day. The night before, they end up having a slew of mishaps that keep them awake almost all night long. The next day, Angelina and her friends have to choose between going to the annual Silly Hat Carnival, a tradition in Mouseland, or rehearse for a very important performance. They make the ultimate sacrifice for their dance and miss the Carnival.

Angelina and her friends are so noisy and messy during lunch that Ms. Mimi has to shut down the Lunchbox Theatre, right before the big Spring Talent Show. When Angelina lets students rehearse in her attic instead, she learns the importance of respecting others first hand.

Angelina is excited to perform “Dance of the Sugar Plum Fairy” at the holiday showcase. She also can’t wait for the holiday party afterwards. But in between final rehearsal and the performance, she and Marco overindulge in candy canes at Mrs. Thimble’s Store, and sample a few too many slices of Mum’s fruitcake...and soon feel awful with stomachaches. They should have followed A.Z.’s example, eating healthy snacks before the performance. While dancing in the holiday showcase, Angelina and Marco struggle because of their stomachaches and are unable to enjoy the holiday party at all!

In her excitement, Angelina invites two friends, Alice and Vici, to see “The Nutcracker.” But there’s one problem: her Mum only bought one extra ticket for her to invite only one of her friends. In an effort to make things right and not hurt either of her friend’s feelings, she lets both of them go and misses the show herself – or, at least that’s what she thinks is going to happen...

Ms. Mimi organizes her students into groups of four, asking them to work together and devise a dance by the end of the day. Angelina, Vici, Gracie and AZ begin the task, but after a very short while, AZ and Gracie disagree about what style of dance they should perform. With Vici and Angelina stuck in the middle of their arguing, it’s up to Angelina to use a traditional folk dance to bring harmony to the proceedings.

When the mouselings are directed to give a report to their class about their hero, Alice expresses her fascination with Anna Mousikova, the famous Russian gymnast. Alice adopts Anna Mousikova’s culture and rigorous practice schedule to emulate her famous hero. Through her endeavor of becoming more like Anna Mousikova, Alice loses a lot of herself and ends up not having too much fun. At the end, she realizes that she can appreciate Anna Mousikova without sacrificing herself.

Gracie has trouble creating an original dance

Angelina’s heart is set on being the Prima Ballerina of “Once Upon a Pillow” as the character of “Fairy Fern.” When Angelina learns that her character is the victim of a magic spell and spends most of the performance sleeping, she tries to convince Ms. Mimi that she cast the wrong dancer. Ms. Mimi promises that if she stays for one rehearsal and still doesn’t want to be the “Fairy Fern,” she’ll make her a “firefly” instead. However, Angelina is given a great surprise at the end of the performance and dances the grand finale.

While learning all about jazz dance, improvisation and poetry, Angelina and her friends get an opportunity to show everyone what they’ve learned. Alice is nervous about getting up in front of the group and gets “tummy butterflies.” Angelina helps her best friend Alice through her troubles and in the end, Alice performs perfectly!

When Marco is chosen to run in The Chipping Cheddar Mouse Marathon nobody is more delighted than Angelina. But her over-enthusiastic support (which includes forming a cheerleading team), makes Marco so nervous that instead of running in the race, he ends up running away from all the fuss and attention.

Angelina opens her very own pretend ballet school in the attic and enlists Polly as her first (and only) pupil. Very enthusiastic and dedicated, Angelina teaches her sister the five ballet positions, which are the building blocks for all ballet moves. Polly, however, is hard to wrangle, causing Angelina to behave strictly to enforce what she’s teaching. This backfires, and Polly quits. At first, Angelina blames Polly for not working hard enough, but Ms. Mimi ultimately helps Angelina realize that being a good teacher means working hard and also making things fun and knowing when to take a break!

When Gracie hears a mysterious tapping in Roquefort Hall, she is afraid that the place is haunted. But soon Gracie, Angelina, Vici, and AZ are inspired to tap and hip hop to the sound, building on the rhythmic pattern each time they dance.

All of Angelina’s friends are vying for her attention: Gracie wants her to look at her fashion book, Alice wants her to play with their magic wand, Marco wants to practice their poem for reading class, and Vici wants to talk to her about the Tap Dance Concert they’re going to see. In ballet class, they all want to partner up with her, and lunch ends up being a challenge to include everyone at the table! When she ends up hurting Gracie’s feelings, Angelina realizes that by including everyone in everything, she can be a good friend to all.

When Angelina finds a Valentine’s card from a secret admirer left at her door step, she and Polly encounter one friend after the other as they try to solve the mystery of who sent the card. At the end, they are in for a pleasant surprise to find that Ms. Mimi, the culprit, gave cards to all the Camembert Mouselings. They repay her with a Valentine’s dance of their own.

Angelina, Vici and Marco mistakenly think Ms. Mimi is getting married. In fact, the original communiqué should have been that Ms. Mimi was going to get a canary. They go to great lengths to make her wedding day special, learning about weddings in the process. In the end, they realize they made a big mistake, but it’s okay. Everyone makes mistakes.

Mr. Mouseling’s hobby as a photojournalist for the Mouseland Herald has brought him to Camembert Academy, with his daughter at his side as his assistant. Gracie’s enthusiasm gets the best of her, and she constantly interrupts the father/daughter team in hopes of becoming featured in the story! The frustrated Angelina comes up with a great idea to curtail her friend’s energy: to get Gracie involved behind the scenes! Although Gracie doesn’t wind up starring in the photos, she and Angelina are both thrilled to see their names in print credited as additional photographers!

AZ boasts that he can perform the complicated "Cheese Roll" dance that his grandfather taught him. He quickly realizes that this dance is a lot more difficult than he expected.

Angelina and her friends need to figure out what kind of music will be played for the Spring Fling Finale performance. The mouselings can’t choose between Flamenco, Hip Hop, Classical and Jazz. Ms. Mimi, who still feels like there’s something missing in her set design, gives her students a short deadline to make their music choice. Angelina has the added responsibility of reviving a dying plant as one of her school projects. With a little help from Mum, she realizes that taking care of living things, and indirectly, listening to all of her friends, takes a lot of care and work. Angelina helps decide the perfect music for the Finale (an ensemble piece of all the different styles of music), and gives Ms. Mimi the missing piece to her set design (the growing plant that reacts to Angelina’s nurturing and everyone’s beautiful music pieces).

Angelina is very excited to be directing her very first Hip Hop Show when suddenly her star, A.Z., falls and hurts his foot! Who can step into his shoes at the last minute? Marco is the number one choice. However, though he can play Hip Hop music, dancing Hip Hop is another thing. The show is in danger of not going on... unless Angelina can come up with a solution in time!
