"The Spore Creature Creator is software that allows players to create their own creatures with a standalone version of the Creature Editor from Spore; the software was one of the first aspects of the game to receive focused development, and underwent ten rewrites since the start of development.
The utility includes a test environment for players to see their creatures go through animations and allowed the player to import other user-created creatures through the Sporepedia at Spore.com. The utility included screen capture and video tools as well, including YouTube functionality. The editor also gave the user the ability to create animated avatars, and output in RSS and embeddable HTML code to facilitate easy incorporation into such sites as MySpace and Facebook."
