Piper is a sixth grade student at Springfield Elementary School and a member of the gang Bossy Riot.

History
Bart first met Piper and her friends, and Erica, when he was escaping from a group of boys. He hid in the girl's bathroom where he found them. The girls then span Bart around. During this, Piper managed to drop the bag of pink spray paint. She then told him to give it back to her, saying it was for Principal Skinner's office.. Bart showed them that he was El Barto and allowed Bart to help them. Bossy Riot then vandalized Skinner's office in an attempt to get sandals unbanned at school. Piper was the one who went into the office and wrote "Sandals Forever" on the wall. After this, Bart followed them to their hideout, the Home Ed classroom. Piper started to explain what they did in their hideout, which included cooking and sewing. The girls then explained what they did to Bart. Bossy Riot decided to let Bart into their gang if he passed a test, to steal Skinner's cell phone. Bart then showed them both Skinner's personal and work phones.

Bossy Riot then went around Springfield vandalizing it and pulling pranks to spread their feminist agenda. This made Channel 6 News where Kent Brockman spoke about it. After this news report, Lisa found out that Bart was part of Bossy Riot and wanted to join in too. Bart then went to join the gang again where he found out that his friends managed to get the female reboot of The Itchy & Scratchy Show canceled. Piper told Bart that Bossy Riot wanted to destroy all the tapes of Itchy & Scratchy episodes as revenge. Bart told them that he wouldn't let them. Bossy Riot then tied Bart up and left him until Lisa found him.

When Bart told Lisa Bossy Riot's plan, Lisa and Bart went to Krustylu Studios to stop them. Bossy Riot planned to dump the tapes in a pool of nail polish remover. Lisa kicked the pool out of the way of the falling tapes which spilled into the audience, causing all the boys to start crying. Bossy Riot then sprayed glitter at them which stuck to their tears. Bossy Riot then escaped from Chief Wiggum, dressing up in princess outfits backstage. Bossy Riot then asked Lisa if she would join them as making the boys cry was hardcore. Lisa accepted and she and Bossy Riot then rode off on their bikes together.
