The opening shows the various members of the design team showcasing various animals.
Shimoda, a newly-hired angel is to be the communications liaison between the team and God. (He looks like a young salaryman, with a hint of dishevelment.)
The crew has another person who's only interested in how the animal looks and another who only cares about how it tastes. I haven't seen their names yet though.
Anyway, the client approves, and the Giraffe is born.
Ueda was called away on a sudden business trip. Hell is, of course, other contractors. (Tell me about it.)
When she returns, she brings Yokota, who has design requests from Hell. He liked the multiplying pandas and would like the team's help designing zombies.
Shimoda tests a device that let's him experience animal society. The society of the Naked Mole Rat, that is. (Approved!)
A request for a regenerating animal leads to a discussion of how aging helps animal populations and the creation of the Immortal Jellyfish. (Approved!)
God wants an animal suitable for Earth and Hell, that surprises even the angels.
The team considers dusting off the Tyrannosaurus, but goes with the Superb Lyrebird, whose mimicry makes the team think God is watching over their shoulder.
Kanamori, designer of birds, is very upset about snakes that eat the bird's eggs. She's looking for some kind of defense.
A nest with a bottom entry would allow the birds in while keeping the snakes out.

And then, Revenge!
