An embodiment of life.

Skulls from animals in ungulata.

• Don't have to be exact, and they can be more abstract, as long as they still look ungulate-like.

ALLOWED:

• Deer, horse, goat, sheep, hippo, and other skulls.

NOT ALLOWED:

• Cetacean skulls, even though they are in ungulata.

If you're unsure if your idea is valid, feel free to ask.
