She's a yellow cream with a stripe down her forehead and a pink dress 
She used to date someone named citrus the rabbit but he broke up with her because someone suggested her to date someone else and she said 'sure', but instead of him being normal about it, lemon square breaking up with citrus was because he was weird despite him not doing any weird stuff, she dating the new boyfriend and citrus being mad at it and wants lemon square back and wants both of them dead.
