When Prilla's human (Sara Quirtle) laughed for the first time, some of her essence stuck to the laugh, making it incomplete. Because of this, Prilla seemed talentless, only later discovering her abilities:
- The Gift: she has the ability to talk in both human and fairy languages
- Human-like mannerisms: Prilla will use human titles and address others as "Miss". She will also apologize by saying "I'm sorry" instead of using the Never Fairy expression, "I'd fly backward if I could."
- Mainland-visiting-clapping talent: she "blinks" to the Mainland whenever a fairy is in danger of dying to encourage children who still believe in fairies to clap their hands and prevent the death.
In the Home Tree's Directory, Prilla's lives in "Room 7P, NNW Branch." "Because her talent was a mystery at first, the decoration-talent fairies did not know what to do. So she received standard-issue fairy furniture [...]" The floor is covered with a grass carpet and colorful flowers, the dressing table and chairs are decorated with pears, the bed is made from daisies and the wooden mirror has flowers motifs. Beside her bed is her favorite teapot, and her foux-mouse slippers.

In Fairy Dust and the Quest for the Egg, when Prilla arrives, many of the fairies thought she was incomplete because she didn't know her talent. Tinker Bell helped show her around Pixie Hollow, while Prilla looked for a talent where ever they went. She slept through most of the hurricane, but landed on the beach later close to Mother Dove. Queen Clarion and Mother Dove selected her, Rani, and Vidia to go on the quest for the egg. She distracted Captain Hook while the others took his cigar holder, helped with the golden hawk, and had to cut off Rani's wings so they could get a mermaid comb. Her and the others then took the objects to Kyto to save the egg. When, Kyto had contaminated the egg she got clumsy children to clap to save it, discovering her talent.
In Fairies and the Quest for Never Land she helped find the tiffen boys that had set Kyto free. Close to the end she went with the other fairies to capture Kyto, so she could get children to clap for them if they needed her too. At the end she went to visit Gwendolyn and brought her gifts from the other fairies.
In Fairy Haven and the Quest for the Wand, during the flooding of Fairy Haven, Prilla flashed back and forth to the Mainland trying to stop the flood by getting clumsy children to clap. She also wished for Sara Quirtle to be complete, it was the only wish that wasn't reversed. Later, she helped Tinker Bell and Beck find Rani-bat in a cave.

In Vidia and the Fairy Crown, Prilla didn't believe that Vidia had taken the crown so she decided to help her clear her name. They first went to the Queen's chambers to question the Queen's helper fairies, then to Aidan, where they learn of the mix up. Twire is next, then Lympia after news of Twire accidentally sending the crown to the Laundry Room. Than Nora, who had mistaken it as on of the Replica crowns. Together with Dupe, they try on all the crowns until Vidia finds the real one. Vidia has them all be witnesses and clears her name. Later, she thanks Prilla in her own special way.
In Four Clues for Rani, Prilla is seen when Queen Clarion announces the Fairy Treasure Hunt, asking what it is. She teamed up with Tinker Bell for the treasure hunt, neither knowing that Rani didn't have a partner yet. Later she and Tink were tricked with the rest of the fairies by the Lost Boys and Peter Pan. Prilla goes to Tink's House.
