Emiculus Cephaloid

The Emiculus Cephaloids are a species of minuscule humanoids, small enough to fit inside the head of an Arquillian. A rogue member of this species, known as Jimmy the Runt, disguised himself as an Arquillian disguised as a Human on Earth, but was discovered by MiB agents J and K and successfully escaped capture. He was subsequently captured by Agent U.
