Haha you're funny n_n The answer is very simple... they live on a different planet [not Earth but Athanatas], & that's a "white plum" that grows there! They have many of the same fruits/veggies as we do but they are much larger & look different especially in color, but there are tons of completely new fruits there too! The "white plum" actually looks more like a Japanese red bean dumpling
[link]I know, there's know way to know that by looking at the picture... she's an rpg character, & you'd have to be familiar with the rpg world to know that n_n *pat*
