Here's the Comic (http://piratemonkeysinc.com/ms2.htm) that gives you a great idea of what Sparklypoo is. The cartoon is really funny.

In case you don't know what 'mary sue' is, briefly, it is an original character in fan fiction that is usually smarter, prettier, stronger, more magical etc. than the real characters and her whole existance warps canon to make her the star. Her being the fanfiction writer, or 'suethor' who created her. Go to deleterius and you'll soon get the idea!
