Koosalagoopagoop also nicknamed Koosy or Koos (born August 6 1988), is Dee Dee's imaginary friend. He is voiced by the late Dom DeLuise. In the episode The Koos is Loose he makes a "Pepe Wrap", which is a tortilla with a tub of meat in it. Koosalagoopagoop makes a cameo in "The Powerpuff Girls" episode "Imaginary Fiend" where Bubbles suggested using him against Patches. However, Buttercup refuses and states that "Nobody likes that Koos jerk!". He is a combined parody of Snufflufagus and H.R. Pufnstuf.
Out of the imaginary friends, Dee Dee and Bubbles likes him
