Sirius
From GryphonWiki
Sirius, often referred to as Taufell, Sirris, or Tau-Tau is well known for making people uneasy. It has a reputation for starting drama- although has never done so from leaking anything from private conversations or screened blog posts, rather, tends to do it by speaking its mind on people, which usually includes the words "Inferior" and "Stupid". Has a thing for making fun of socially inept furries.
Is often depicted as some horrid cross between the Cheshire Cat from Alice in Wonderland, a pair of tattered toesocks, a purple slinky, and the things nightmares are made of. It may believe it actually is this from time to time, if such a thing suits its purposes.
It likes tofu, David Tennant, and being more intelligent than everyone/thing else. It lives in Australia someplace.
Exo does what it says or it gets the hose again.
