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 Mexican wrestling mask, wings, and a yellow dangling 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.
