(Sung to the tune of "Rasputin" by Boney M) StarGleamStar

There lived a certain Sue, in fanfic long ago

Her fur was almost urple, her eye color was rainbow

Most agents looked at her with terror and with fear

But to the Suefluenced canons, she was such a lovely dear

She could preach the Bible like a fundie

With homophobia and misquoting

She was the kind of Cat-Sue

Agents would abhor

Star, Star, StarGleamStar, lover of her great-grandpa

Didn't want noone to be gay

Star, Star, StarGleamStar, forest's greatest love machine

'Till she realized she wasn't straight
