Missmouse2013, called Mouse or Miss, isn't actually very active on the forums. But she is the best friend of Catglove and is writing a Neopets novel. (Which is why I added her. To make her more active. :P)
She is a fan of Homestuck, and is one of the reasons Kat is too.
Mouse's Neopets username is beans_45_6_6.
She is an active member of the site JNF.
