Marie and Riley are siamese twins and they are minors characters of the series My Giant Friend.
Marie and Riley are as alike as two drops of water. They are ironically represented with Chinese features. They have the same hair and the same clothes.
Marie and Riley follow Jenny like her shadow and mimic her every move because they like her very much even if they have not a lot of personality. And, like Jenny, they hate Linus but they like Boom very much.
