If you want a version with battle Damage, try the "Doomed Horns -Damaged":
Wish the horns where bone colored? Steel? Purple with Pink Polka Dot?? Well then, buddy, start Deriving! Make your own version, and even sell it the catalog for a small markup over my original, and keep the extra profits for yourself! You can express yourself AND earn credits at the same time. How's that for a sweet deal? You'll need a full account on IMVU, as well as a copy of Previewer. You can find out more about Deriving on the IMVU's Education Center. Below is the template you'll need to get started (Right Click and Save As to your computer):
This is the actual Texture map used on the Horns. Use this to make small changes, like color or shade. Keep in mind that this image is mirrored on the right and left, so it's best to avoid numbers or letters in your new design:
This is the Wireframe Template for the Horns. This shows you exactly how the Texture map adheres to the structure of the model. You'll need this if you want to create a completely new Texture map:
To add sound, I highly recommend you download and use Audacity. It's a free sound editing tool that can export out OGG sound files. OGG sound files compress down to less then 1/10th the file size of WAV files. SO USE OGG FILES!!! You can download it here:

Also avoid looping sounds, as they tend to get annoying to listen to very quickly. Try to keep your volume levels low as well, as IMVU tends to over-amplify all audio playback to near ear-bleeding levels.
