One of the creatures was a large pterodactyl like creature, the round ones are like floating jellyfish - they are kinda funny to see bob around.
The views like that moons are wild and it's hard to believe it's all to scale!
Gravity varies from place to place, they did a good job with it. A moon like that one is probably less than .3gs. Tons of fun to jump and boost pack around!
