Sterrance
From Homestar Runner Wiki
In the Strong Bad Email "animal," Strong Bad settles on Sterrance as what he would look like if he were his own made-up animal. This is decided only after a series of other failures (documented in Made-Up Strong Bad Animals). He has Strong Bad's face-mask-shaped thing, wings, and a yellow dangly tongue.
Strong Bad thinks that Sterrance is way cuter than his old washed-up The Cheat, and this insult starts a fight between the two creatures.
