Otter's Rock

We know nothing about Orion anatomy. But look at Cyd's cool elegance in that dance--with the bobbed hair, at some points she really does look Vulcan. Tall, elegant, cool. And remember, Vulcans have green blood--it makes sense they'd have green-tinged skin.

Though, if you'll notice, she's actually taller than Gene Kelley even without those heels. Look at how much she's keeping her knees bent all the time to look about the same height or shorter! And the way the dance is choreographed, it looks cool and not stupid.
