The three headed siamese triplet sons of the chicken form outer space are one-shot Courage the Cowardly Dog villains who appear in "Son of the Chicken From Outer Space". They were sent by their mother to destroy Courage and avenge their father, the Chicken From Outer Space. The three try several unsuccessful attempts to kill Courage throughout the episode, but by the end they break down in tears and explain to Courage that they need to kill him or their mother won't let them come home. Being a nice dog, Courage helped them fake his death so they could convince their mother that they had succeded. In the end, the three thank Courage for his help before returning home.
