Nuts hails from the Palmier Kingdom, a realm ravaged by the Nightmare organization. He travels to Earth with Coco seeking humans capable of becoming Pretty Cure warriors. Initially captured by Nightmare and imprisoned within the magical Dream Collet book, he requires rescue by Cure Dream and her team. After gaining freedom, Nuts actively supports the Pretty Cure team in their mission to gather the 55 Pinkies essential for restoring the Palmier Kingdom and granting wishes through the Dream Collet.

In *Yes! Precure 5 GoGo!*, Nuts gains the ability to transform into a human form. This allows him to attend school alongside the Pretty Cure team members, fostering deeper bonds and integrating him into their daily lives. He aids the team's search for the magical Rose Pact and participates in battles against the Eternal organization, contributing to the protection of the Cure Rosegarden.

Nuts maintains his supportive role across multiple *Precure All-Stars* crossover films. He joins characters from across the Pretty Cure universe in *Precure All Stars DX: Minna Tomodachi—Kiseki no Zenin Daishūgō* for a collective battle against a shared enemy. He returns in *Precure All Stars DX2: Kibō no Hikari—Rainbow Jewel o Mamore!* for large-scale ensemble battles. In *Precure All-Stars DX3 Mirai ni Todoke! Sekai o Tsunagu Niji-Iro no Hana*, he is part of the united effort by all Pretty Cure teams to defend the Prism Flower from the entity Black Hole, reinforcing his established role as a recurring ally in franchise crossover events.
