Most of the creatures you see in the game come from other players. Spore uploads their designs to an online database, and then your game chooses from these options every time you encounter another creature or vehicle. You can also download individual characters yourself. To make this transfer speedy, programmers boiled all the info needed to recreate a character—such as size and personality type—into a short text code, like virtual DNA. Then they included this text in the metadata of a small graphics file, like the one shown here, so you can import an entire creature, mannerisms and all, just by downloading a small picture.
