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 only decided after a series of other failures (documented in Legendary Strong Bad Animals). Sterrance kind of looks like a "doodle" from Disney's online MMORPG "Toontown." He somewhat resembles the cartoon character Stimpy, but has Strong Bad's face-mask-shaped-thing and a yellow dangly tongue. Just as Trogdor has one arm, Sterrance seems to have one wing. Strong Bad thinks "Sterrance is way cuter than that stupid ugly old washed-up The Cheat I used to have" and lets Captain Past-His-Prime, The Cheat, know it. This starts a bit of a fight between Strong Bad and The Cheat, which is as-yet unresolved.
