Actually there is a dead narwhale right at the beginnig of the animation. Sadly for this animation I did not see any other scene where I could place him. I will make it up to him in the next animation though.
Freaking Mechawhales... never thought of the idea, at least, not like that. They are driving suits! SUITS! It's not parts, like, replaced fins, or armor that fits perfectly around the body, well they fit nicely around the body here, but.. the armor doesn't Look like the body of the whale. It looks like something you'd well see a human in, but, they are for whales.
