The costume guy who did a lot of creatures for us came to the studio and said, 'I have to show you this new creature,' and it was this kind of lumpy thing that was orange and misshapen and it was real low to the ground. He put a rubber chicken out in front of the thing. He climbed inside this suit and on his hands and knees he brought this creature over the chicken and the chicken disappeared. After he passed over it, some bones appeared out the back. Gene said, 'I've got to find a way to use that,' and he came up with the Horta.
