Princesses, unicorns and silly string were part of a huge parade on Saturday afternoon as nearly 100 cars, cruisers and fire trucks turned out for Dartmouth resident Ellie Art — but it wasn’t just in honor of her recent sixth birthday.

The party parade was held to celebrate Ellie’s last day of chemotherapy on Tuesday, and her whole family — including mom Audrey, dad Pete, and sisters Penelope, 3, and Julia, 10 — sat in the driveway to watch as colorful car after colorful car made their way through the neighborhood.

Ellie was diagnosed with acute lymphoblastic leukemia and began chemotherapy treatment two years ago, when she was just four.

“She has her port getting removed on Thursday, and other than follow-ups and labs to make sure everything’s still good, she’s done,” said Audrey. “No more medicine.”

Before the parade started, Ellie did a little celebratory dance when asked how it felt, saying with a grin, “so good!”

As for the number of people she thought would be able to come out for the event, she aimed high. “A million!” she said, before listing the friends from school she was hoping to see. 

And although the weather was a bit chilly, it didn’t faze her. She said that the morning snow shower was because Elsa from Frozen wanted to wish her luck.

Bubbles and unicorns — Ellie’s favorite animal — abounded at the parade, along with dogs, candy, gifts, and even silly string.

And all her friends from Cushman School came as well — including Principal Melissa McHenry.

“All her friends from class came, and her teacher, and her principal,” said Audrey. “One of her buddies who was in treatment who lives far away came,” she added. “It was a lot of fun!”

Alongside friends and relatives, famous movie princesses Cinderella, Belle, Moana, Rapunzel, and even Spider-Man showed up after parading all over town to cheer up residents during the day.

The beloved characters — Dartmouth High and Middle School kids in costume — spent six hours driving more than 60 miles around town to bring a smile to kids who are tired of isolation, finishing at Ellie’s party.

Dartmouth High School sophomore Sophie Waite dressed as Cinderella for the occasion, and said that despite the cold and the long hours, “it was really fun!”

“It was really fun to see all the little kids, they were so excited,” she said of parading around town. “It was just really nice to see kids happy, because they probably don’t really understand what’s going on. So it’s really nice to do something for them.”

Waite will be donning the costume again in two weeks for another princess parade, right after finishing her AP tests online.

“I’m excited,” she said. “But I hope it’s a little warmer!”
