Poppy is a lead, a relentlessly upbeat — if slightly naive — Troll whose father King Peppy saved his subjects from the Troll-hungry Bergens. Despite this, Poppy is incredibly noble and responsible as she risks her life to go on a perilous journey to save her friends. As she and her group of nine friends, the Snack Pack, face their biggest challenge ever, Poppy is faced for the first time in her life with a problem that apparently can't be solved with a song, a dance and a hug. But after some hilarious attempts at saving the day, Poppy discovers that being true to anyone else is always the best answer.
She has flamingo pink skin and has sparkles on both cheek and wears a blue dress with a green hairband with flowers on her pink hair. She also wears a bean sprouted ponytail with a light blue rubber band.
When she was a baby she was naked except for her headband with a flower on it.
In the beginning, Poppy is only a baby. She is four at this time and later she is 24 years old. She is to be served to the young Prince Gristle as his first troll. However, she is replaced with a wood decoy and saved and delivered to her father King Peppy, where she is led out of Bergen Town by him to safety through his hairnow energetic and happy adult Poppy throws a party to celebrate the escape from Bergen Town, but this party attracts the attention of Chef, a Bergen who was banished from Bergen Town by King Gristle Sr. for the Trolls escape. Chef captures all of Poppy's friends in the village, though Poppy, Peppy and the majority are able to escape. With Peppy and the remaining Trolls reluctant to go to Bergen Town to save the others, Poppy recruits a pessimistic Troll named Branch to help her.
Upon arriving in Bergen Town, Poppy convinces the scullery maid Bridget into freeing the captured Trolls, in return to get her a date with Prince Gristle, now known as King Gristle Jr.. She tries to convince Branch to sing, but he reveals that the reason he doesn't sing is because of Grandma Rosiepuff being killed by Chef. Poppy and the other comfort Branch. He agrees to help, but still not sing. Using their hair, Poppy and the Trolls, make Bridget look like she has long colourful hair and whisper her on what to say. This succeeds in getting King Gristle becoming attracted to Bridget (who uses the name of Lady Glitter Sparkles). Later, Poppy sees one Troll named Creek (whom she had a crush on) supposedly being eaten by King Gristle, but later sees him trapped inside the King's jewel. The Trolls steal the jewel, but find it empty. Just then, Poppy and the Trolls are captured by Chef and discover that Creek has turned against them to save himself from being eaten. Creek then takes Poppy's cowbell and uses it to trick Peppy and the other Trolls in the village to come out of hiding, before they are captured by Chef and the other Bergen cooks.
With all the Trolls captured and ready to be cooked, Poppy loses hope and turns grey along with the other Trolls. Branch however, is able to restore Poppy and the other Trolls' colors by singing Cyndi Lauper's "True Colors" and admitting he loves her, which she reciprocates. The Trolls are then rescued by Bridget and reveal to King Gristle that Bridget was Lady Glitter Sparkles and say that Bergens don't have to eat Trolls to be happy. The King agrees to this and now the trolls and the bergens are no longer enemies.
At the end of the film, Poppy is made Queen of the Trolls and Bergens, and shares a romantic hug with Branch.
