Many people think that Bonney may be Big Mom’s daughter and I agree. Like Lola and Purin, being named similarly to sweet foods: Lolly and Pudding, Bonney is also named similarly to a sweet food. Jewelry Bonney’s name can actually be phonetically pronounced by Japanese people as:
‘Jujubes Bonney’. Jujubes are French Candy/Sweets , fitting the French theme of the Big Mom Pirates. Also, another French sweet food, Bonbon – is similar to her name. Her name clearly fits.
Bonney has bright red lips similar to Lola and Big Mom, whom are likely her relatives. They all have pink hair and all of them can eat excessive amounts of food as well as ALL THREE of them having the same heart shaped lips! She has also been shown on a Cake Island/Ship, likely associating her with Big Mom.
