Sweet Pea

Sweet Pea (スイトピー) is a member of a tribe of Kuja living on the island of Amazon Lily. She was first seen accompanying Marguerite and Aphelandra when they found the mushroom covered Luffy.

Amazon Lily Arc
After they found Luffy, Sweet Pea and Marguerite went to wash Luffy after burning off the mushrooms that covered his body, during which she tried to pull off his "Manhood", thinking it was a mushroom that survived being burned. When Luffy was placed within the island's prison, Sweet Pea kept his straw hat as a souvenir, prompting Luffy to reveal his rubber powers to take it back after coming to.

During Luffy's execution, when Marguerite confesses to saving Luffy, Sweet Pea comes forward too, and is turned to stone along with her. Luffy puts her petrified form out of harm's way so that if there is a way to return her to normal, he can save her.

After Luffy defeated the Gorgan Sisters, Hancock, at Luffy's request, changed the petrified Kujas back to normal. Sweet Pea is then seen enjoying the party with Luffy. When Luffy leaves Amazon Lily, Sweet Pea is among the Kujas to bid Luffy farewell.

Trivia

 * She is named after the flower Sweet Pea.
 * Her name is a parody of herself, as the sweet pea is a petite, pretty flower which contrasts to her large and extremely masculine figure.
 * As a joke in the anime, Sweet Pea is given a very masculine voice to mimic her appearance.
 * She has a habit of stating that whatever they need to do to is a "saga". An example would be when Luffy was going to be brought back to the village. She announced that it would be "the saga of 'we must hurry and bring this her back to the the village'."
