Skooks is Orpheusftw's version of Scooby-Doo from "The Misadventures of Skooks".
He is usually similar to Scooby except that sometimes he goes into a monstrous rage in which he is capable of such feats as scaring the shit out of Shaggy and Velma or even defeating the Penguin with a single blow. He can also grow an arm out of his mouth, which isn't as helpful as you'd think.
Relationship with Shaggy
Skooks has a very close relationship with Shaggy, who admits to being a "dog lover". This was first suggested when Freddy saw them getting to 2nd base in the remains of a crashed plane. However, this was revealed to be merely a dream. Later, though, they have been shown engaging in this behavior in real life, as well as Skooks shitting on Shaggy.
