Environmental assets from an early version of the game. They aren't in the game anymore, so you will have to complete the adventures of Tiny Bunny Family in your mind. (They go to the moon and meet space bunnies.)
Oh man...I wish I could do this level of detail in the games I help make. I work for a company and basically we're told we can make ONE stick and ONE rock and then just flip/rotate/repeat it. It makes our games look pretty tiled. Not NEARLY as cool as this!!
