Stinky is the brother of Stretch and Fatso, as well as the uncle of Casper. Stinky's special talent involves supernatural halitosis and body odor, which he prefers as his means of frightening "fleshies" who cross his path. He is also an inventor.
He, like his brothers, cares deeply for his nephew and enrolled him in Scare School so he can learn to be scary and doesn't get banished to the Valley of the Shadows. He sometimes appears at Scare School to make money.
Stinky is sligthly shorter than Stretch with big teal/blue colored eyes.
He is described as being a "blabbermouth know-it-all". He is nasty to humans (except Jimmy) but is usually nice to other creatures.
Stinky is very close to his brothers and is always seen with them. They always scare people and pull pranks with (and on) each other, they also tend to hug each other when they are happy or upset.
Casper is Stinky's nephew. Stinky loves Casper dearly and sometimes refers to him as his favorite nephew. He knows his nephew should be a lot scarier than he is but has a tough time being stern with him.
Stinky is nice to Mantha and Ra since they are his nephew's friends.
Stinky is fond of Thatch due to their love for pranking people, although Stinky is unaware of Thatch and Casper's rivalty. https://www.youtube.com/watch?v=k6CH8DfCv0w
