A Shield and Beast

[SlackerDrummer]

While the visual might be, uh, subject to interpretation, the blazon would read, azure upon a mound of earth in base proper a zebra forcene, also proper.

Perhaps with the motto: I've earned my stripes.

I think I'd compress it further to azure on a mound of earth a zebra forcene proper. It is understood that everything after the word azure and before the word proper is...well, proper.
