Sherlock
From Homestar Runner Wiki
Sherlock is the star of Sweet Cuppin' Cakes. He looks like a strange, egg-shaped, blue cow and moves by hovering like a helicopter. His language appears to be a sort of weird, obscure murmur. It is perhaps for this reason that he never speaks with any of the characters; instead, most of his lines are apparently soliloquies. His main goal in life is to get The Worm out of its hole in the ground. He is very, very bad at this.
It was learned that his name was Sherlock from the strongbad_email.exe DVD. Previously, he had been referred to as Cowcopter in the Sketchbook. If it weren't for The Brothers Chaps mentioning it, his name would never be known, as it was never mentioned on the site itself.
On the cover of the album "The Freewheelin' Eh, Steve" (seen in Weclome Back), the song Talkin' Trying to Catch a Worm Blues is credited to Fresh Juice, so this may be his pseudonym.
