Shreako is one of the Boo Brothers, a group of three ghosts who act as incompetent ghost-busters.
Shreako resembles a humanoid, with a thin ghostly white and translucent body, a beak-like nose, and a tail-like end. He wears a green aviator's cap.
Shreako is somewhat goofy and crazy. He doesn't like it when Meako sticking his head right through him and Freako sticking his arm right through him. When they do, he laughs crazily and quickly and says, "Don't do that!"
Powers and abilities
Being a ghost, he can fly and pass through walls, as well as telephone lines. He can also turn his head into a lightbulb and turn into a floating head for his "scary face" act. He's also pretty good at playing the piano.
Scooby-Doo Meets the Boo Brothers
He and his two brothers were hired by Shaggy Rogers, Scooby-Doo and Scrappy as ghost exterminators to rid the Beauregard mansion of the multiple ghosts. However, he and his brothers mostly just messed things up until Shaggy got fed up and fired them, at which point they started crying and told Shaggy that they were orphans and they needed the job so they could earn money to get their own place. Shaggy reconsidered and rehired them, but telling them they had to "shape up or ship out." Eventually, they saved Shaggy, Scooby, and Scrappy's lives, lifting their sunken boat out of the water and preventing them from drowning, and got the three back to the house in time to catch T.J. Buzby before he stole the treasure. Shaggy, Scooby, and Scrappy left the Beauregard house to them, so they finally got their own house.
Shreako: Have no fear, Shreako is here!
- Shreako is supposed to be a parody of Curly of the Three Stooges, because of the voice, personality, and the "Nyuk, Nyuk, Nyuk" catchphrase.
