She-Rilla (left) & He-Rilla (right).

The Space Gorillas are characters in Rocket Monkeys. Gus and Wally are highly jealous of them, and often compete with them. Their names were originally thought to be He-Rilla and She-Rilla, being male and female respectively, but they may be just nicknames, as in "Switch Day" their real names were revealed to be Humphrey (the male one) and Ingrid (the female one).
