Does it fit the iPad Pro 12.9?

Yes. Burga lists it as fitting the Apple iPad Pro 12.9. Check your model generation before ordering, since 12.9-inch iPad Pro sizes changed over the years.

Does it have a stand?

Yes. The case has a built-in stand, so you can prop the iPad up for watching or typing.

Is it a keyboard case?

No. It is a protective case with a stand, not a keyboard case. You would need a separate keyboard.

What does the Sunny Bunny design look like?

It is a yellow and multicolor bunny print. It is a statement design rather than a plain or neutral finish.

Burga is the only store listing it new.

It is a single-store item with no other new listings to compare against, and it costs more than a plain printed tablet case. You are paying for the Burga print and the built-in stand.
